Well, I think AOTC Kenobi would probably take on his younger self, and win, while Anakin takes on Qui-Gon, but loses after a good fight.
If Kenobi can take down his younger self quick enough, he might be able to aid his apprentice to finish off Qui-Gon, but if not, I can see him and Jinn facing off against each other in a long arduous duel, but I can't see Kenobi overcoming his former master.
