Hand 1 you really should raise the flop.

Hand 3 is different after your read from Hand 2. It looks like Villain is loose, but comes alive when he hits a hand. I think he would've raised you with any good pair on the flop/turn, so minus a slowplay you are up against JT or a flush. I wouldn't be confident enough to not 3-bet. In any case, the turn bet is really iffy (probably bad) against a loose player.
