Let's put the pieces together in a realistic attitude in which we assume that producers are not selling metaphysical stuff with this happy-crying murderer.  Before presenting my theory, I want you who are interested in storytelling stuff to think about this question: 
Imagine that it's a written novel and Lisbon is the narrator of this story, would this final episode be different?  
I just want you to think about it.

Anyway; let's ask our ordinary question:

How can Red John know exact list of seven names of Patrick Jane?

I think non of these seven names announced by L.Martins is R.J. Moreover, P.Jane's list is different or even there is no list of 7 names.  Watch the final, s5e22 carefully. P.J regularly incepts a curiosity into Lisbon's mind without satisfying it.  If P.Jane actually does not Lisbon to know this seven suspects issue, Lisbon would not have any clue about it.  

Watch the final part of final episode again, Red John's declaration does not say that there is 7 names but "a few names". It's definitely the same trick of Patrick Jane. A couple of week ago, he designed his "investigation room" with the awareness of Robert Kirkland's move. And yes, he simply incepted these seven names into Kirkland's mind then Kirkland's team of special agents edited the video according to these seven names.(of course with the presumption that he is accomplice of Rj) 

I argue that the original version of the L.Martins video contains more suspects and probably (no reasonable evidence but a possibility which is reasonable in itself) it's 30 as CBS website gives it to us but now we are  tricked by Red John who debugged other names and wanted to show P.J that "I'm much more superior than you!". At the twist, our first impression is supported by this cap ;

and producers want us to feel exactly the same as Lisbon. They want us to think the metaphysical possibilities, "special powers", they constantly bolds a"faith of metaphysics in this murderer" in us as Lisbon illusioned by Sean Barlow. And they tricked us at the final. However, what makes this show "watchable" is the post-modern "unreliable narrator" technique in which the narrator and equivalently we are double tricked just like Dr. Watson of Sir A.Conan Doyle.

Shortly, I think P.Jane does not know who Red John is but now he knows that he fooled Red John for gaining advantage and he fooled Lisbon for the sake of season finale. I guess, whole trick will be unfolded at s6e1 in which we see that P.J.'s list is not 7 names but 30 names as CBS weirdly and surprisingly served us.

I know we've only seen him in one episode, but I think it could be Danny Ruskin, Jane's brother-in-law.

I was thinking and I realised that RJ seems to know a lot about Jane's past, indicating that he may have been involved in it somehow and at first I thought Jane may have a brother or sister that we've never met, but that would be rather disappointing, wouldn't it? But what if it was his wife's brother? 

In the one episode we see him in (Cackle-bladder Blood), we learn that Danny grew up on the same carnival as Jane and that he later became a con-man. This would explain why RJ knows so much about Jane's past. 

We also learn that Danny dislikes Jane a lot for two reasons, taking his sister out of his life and then for getting her killed by taunting RJ on TV. 

But really, Danny didn't seem like the kind of person who would do that. He is a con-man though. He could hide things well. Maybe he thought that if he couldn't have his sister in his life, neither could Jane. And maybe his hostility isn't towards Jane getting his family killed, maybe he hates him because he taunted him on live TV? 

Anyway, I did a little research and I found out three interesting things.
1) When people leave the carnival they don't get to come back. People hate it when others leave and the phrase 'dead to me' is often used. I know this isn't substantial evidence or anything, I just thought it was interesting and maybe a small hint at who RJ is.
2) This point is a lot more interesting. We all know how RJ uses the alias Roy Tagliaferro. Well the name Roy means red. and Ruskin has the meaning 'red-haired'. We know from Jane that people tend to use aliases that are similar or have a connection to their name. 
3) After reading about the Roy-Ruskin-Red connection, I decided to see if Daniel and John had any connection at all. The name John means 'God is my judge' and the name Daniel means 'God is gracious'. I know this isn't a very definite connection, but if RJ is at all religious, it could be a possibility.

Also, remember how 'RJ' told Jane how Angela smelled before she died. Well it was done with a car bomb, so it's likely that he wouldn't have come close enough to her to know that. But someone who grew up around Angela would maybe have memories of her perfume how she would often smell. 

Danny also fits the physical description of RJ very closely. The actor, Kevin Rankin, is 1.82m tall which is 5 feet 11 and 21/32 inches (points to google calculator) or just under 6 feet? We also know that he is younger than Angela (his sister), but he can't be much younger as he isn't much younger than Jane. His voice also fits the description of RJ's;soft and high-pitched.

Finally, in the same episode we meet him, Jane describes him as a 'sociopath, like all good con-men' and he often describes RJ as a sociopath too. So, does Jane maybe secretly know in his mind, as we know that RJ can hypnotise Jane?

So yeah, that's my theory on RJ being Danny Ruskin.

Red John is a tag team duo of Rosalind Harker and her sister Grace Van Pelt. 

HI : RJ is PJ's father!

I don't remember exactly in what episod of the mentalist season 3 I just thought that RJ may be PJ's father, WHY ?
We don't have a lot of informations about him : is he still alive?  The last scene i saw of PJ's father was a memory scene of PJ refusing to scammed an old women with her sick daughter; then comes a meeting scene between RJ and PJ when RJ comes near to PJ and told him the poetry, RJ was bigger then PJ as we cas see at this scene ( PJ father is also a tall men then PJ), and with this last episod i am definitly sure that is him : who can know about a happy memory of PJ childhooh that he never told to anyone? his father was there as PJ says himself to teresa when he remember the song.

AS we know : RJ is more intelligent then PJ, and especially he knows what PJ could think or do anytime in any circonstances, he's someone who got power to manipulate people.
Why will he make PJ suffer by killing his wife and daughter :  REVENGE, because PJ left him and runs away when he was young maybe, or simply to show him that he's always the intelligent and powerful, isn't PJ's father who show's him how to act like a real medium. 
My theory is done, so what do you think about?

IBRA IS RED JOHN! HE IS! LOOK AT HIM! THE WAY HE TALKS TO JANE, THE WAY HE WALKS IS IBRAAAAAAAAAAAAAAAAAAAAAA!!!!!!!!!!

After watching the S5 Finale I have a few thoughts:

I think the video Lisbon and Jane watched was made by Jane and Lorelei.
Something about it did'nt sit right with me. I think that Jane got a clue from RJ about the memory from his past and made the video with Lorelei and then planted it with the woman from Child Services under hypnosis. She was not a piece of RJs plan. Jane would not let her go unaccompanied in the cop car where she was able to kill herself is she had any info on RJ. He didn't seem phased when she said she wouldn't talk.

The question is why? I think it is just to paint Lisbon as a suspect along with the broken arm without much explanation etc. I believe Jane is trying to keep Lisbon safe by throwing her off the trail. Jane loves Lisbon and knows that RJ will hurt her to get to him.

In addition I think i have figured out that:

DR. TOWLEN MORNING IS RED JOHN.

What we know about him:
-over 30
-doctor so he is intelligent, clean, organized, wealthy
-caucasian 
-knowledge of human body including death

In Janes book where he had suspects written he had Dr. Mornings name and underneath he had family doctor and DECEASED?

The question mark is a big clue, if the frozen mans body had be I.D.'d and Dr. Mornings there would be no need for the question mark. 
Dr. Morning as RJ also explains how RJ knew about Janes childhood memories, I think Dr. Morning was Janes doctor in the insane asylum. Serial Killers love to get close to the crime, Jane went crazy and RJ is obsessed with him, so what could be better than seeing Jane everyday. That is how RJ knows the secret, Jane doesnt even know he told him in the asylum. RJ then hypnotized him to forget his face/name therefore the name Towlen Morning doesn't remind Jane of the hospital.

EVEN FURTHER EVIDENCE:

Ever notice of RJs accomplices seem to be random? Men/women, dark hair/light hair etc They seemingly have nothing in common other that some previous trauma that makes them easily manipulated, so what is the link?

Dr. Morning is their doctor. All the accomplices have seen the same doctor, that is how he can have control over different people in different areas. He may work in walk-in clinics in numerous locations and is able to hypnotize any weak people to do his work. It all makes sense.


All the evidence points to Dr.Morning - let me know what you think? 

Well done PJ!!!

I know that Bruno said no more twists, just facts. But it is a fact to me that PJ's bait has been taken by RJ. There is that smile on P's face when he picked that toothpick  from the floor... I think (as some other people on this site) that P has his own list in his mind with fewer names... Bret Partridge? Why not and it is not dissapointing at all! However it is so obvoius to us and come on, Patrick would notice same things!!! Bob Kirkland? Same thing! I  definitely wouldnt be disapointed!

Now, there are names that are missing from the list like Walter Mashburn... Hmmm But there is someone else that to me is even more sppoky than RJ... And especially after yesterdays episode... I did ask before How  Kristina Frye knows that PJ's daughter was asleep when she was being murdered? Fine maybe RJ told her. But  How the hell she knew that PJ was wandering about it in the first place?????  I have thought about it and dont know the answer to this day. Maybe it is something normal aftyer loosing a child... Can't tell. And again now! A happy memory from PJ's childhood ... Memory that even he didnt know he had... Spooky again!! Are Kristina and RJ real psychics?? Hey Patrick said no  such thing!!! This little thing kind of leaves me hanging and Im sure there will be some stuff (not twists) that we have all missed. And if BP or BK is Red John I say I wont be disapointed!! mentalist is one of the best TV series I have ever seen! Keep me thinking, speculating and guessing! WELL DONE Mr Heller and team!!!
