Couple hands 200NL -Bodog

[elcheapo]

1. Mp (200) raises a few limpers to 9$ and i reraise to 35 with kings. Folds to him and he pushes within 2 seconds. Can I fold?
2. Raise it up utg with 57 hearts to 8$ and get 5 callers. Flop is A8h9h. I check hoping I can hit my hand cheap. Checked around and the turn is an offsuit 6. I bet a lil less than the pot and my loose aggressive callers all fold.
Lead for 20, check again?? I didn't want the board to fill or a 5 or 7 on the river.
3.I limp with J2 suited (first mistake) and seven to the flop. Board comes 10xsxs and BB leads out for 2$, four callers to me and I call?? Turn brings the flush, bb bets 2$ and four callers to me and I raise to 30$??,bb calls and utg minraises. Can I fold for 28$
