Here are a few hands from $100NL. I'd appreciate any insight on if I lost value anywhere (by not folding when I should have, or by not raising when I should have)

Thanks!

HAND 1:
-I probably should have foled to the PF raise, if I didn't think I could
play agressively on an A high flop
-I definitely played this hand too passively. Is this a river fold after
three barrels from villain?

HAND3:
-flat call by villain on the turn leads me to believe he is also on flush draw
-flush draw completes on river and he leads into me. I have a weak flush, is there value in raising? I usually don't like raising, if a push by villain would make me sick..

HAND 4:
-I usually re-raise this preflop strong, but decided to mix it up and flat call here preflop
-how quickly/slowly do we play this hand?
-note, villain took a looong pause after my check raise on flop before calling. After this call should we slow down worried about set, KJ?
-I put villain on AK by turn and decided to open push, thinking he would call with TPTK and straight draw
-good/bad?
