Mark Hamill as Luke Skywalker - Jedi Master, think of him as being in the Yoda role from the OT and PT. He could quite likely not be directly involved in the action. Harrison Ford as Han Solo - Retired but Extremely Dangerous, perhaps he kicked a hornets nest or something... I really am not sure what Harrison Ford's role will be. At his age, maybe he's an admiral or something. Harrison Ford might want a death scene. Carrie Fischer as Leia Organa Solo - Parent and Politician, probably high up in the New Republic either acting as a chancellor or president... or perhaps she's a bit lower down and part of a diplomatic corps or something. Late-teen female, independent, good sense of humour, fit. - Apprentice #1... aka the new Protagonist. Either this is a daughter of Luke or a daughter of Leia and Han. Does not fit any known EU character (except maybe Allana, which I'm going to put down as being just as likely as hell freezing over). Young twenty-something male, witty and smart, fit but not traditionally good looking. - Apprentice #2... aka the new Protagonist's brother or cousin. Either he's a son of Luke (not traditionally good looking kind of goes with that) or Leia and Han. Could be Ben Skywalker, but again I'm not going to say this is likely. A late twenty something male, fit, handsome and confident. - Scoundrel, Smuggler, or Military type that acts as an ally and support. Much like Han Solo did in the Original Trilogy. Likely Apprentice #1's love interest. Seventy-something male, with strong opinions and tough demeanour. Also doesn't need to be particularly fit. - The Villain, probably a purely political threat... the Jedi aren't exactly the most liked bunch in the universe after all. This doesn't necessarily mean that we won't see jedi casualties and warfare. A second young female, also late teens, tough, smart and fit. - Apprentice #3... Friend of Apprentice #1 and likely love interest for Apprentice #2. She could be a Solo or a Skywalker depending on if Apprentice #2 is, but likely isn't. Forty something male, fit, military type. - Jedi Knight or Military Leader, likely the immediate master or adviser to our protagonists since Luke almost certainly has the Jedi Master Yoda type role. A Corran Horn type, or something similar perhaps? Thirty Something male, intellectual. Apparently doesn’t need to be fit. - Jedi Knight or Scientist, I'm going to go out on a limb and say that if we didn't get the NJO and it's follow ups... this would be Jacen Solo. As I'm going to ignore that... I have no idea who this will be.
