U mean 4bet pre in hand 1? I wouldn't against a seemingly nittastic unknown. Small sample but it's unlikely he'll turn out to be a squeezehappy 26/24 type. 200bbs deep as well, trying to stackoff here PF would be a hudge error. Regarding the hand itself, i'd shove the flop after the c/r.

As for the other hands I don't wanna comment too much (don't post results!!!11!!!), but I will say that a 15/7 villain is prob never calling a 3bet w AX, this is like 44-TT >95% of the time.
