600nl facing a turn raise in marginal situation 3 hands

[NaDaChip4U]

hand1: not much reads on villian,have him 28/13 in 80 hands. effective chip stack is $630.
btn raises to 18, i raise As Js in sb to 72, btn calls
flop: 5d Jh 9s.
i bet 108 btn calls
turn: 3s
i check he bets 240
whats the best way to play this type of hands in reraised pot on flop? and turn?

hand2: villian is tag, havent seen him getting out of line. prob a regular. i raised flop because he bet so small and was thinking he might have lower pp or two over cards type of hands, or weak J. effective stack is $620
utg raises to 21, i call with 6c4c on cutoff and bb calls
flop: 6s Jc 9d ($66 in the pot))
utg bets 36 and i make it 114 utg calls
turn: 4d
utg checks i bet 156 utg moves all in
hero??

hand3: think villian plays little passive pre( no raise after 40 hands), but havent played enough to know for sure. effective stack is $650
mp limps, btn limps also, sb folds i check on bb with Js8s
flop: Kd2s5s
i bet out 18, only btn calls
turn 8h
i bet 48 btn raises to 168
hero?? the way this played out he prob got something, but is this spot good enough to raise him as semi bluff? since i was playing tightish poker on this table. or is it better of fold or call?
