Multitabling so no real reads, MP2 a little loose, CO seems solid.

Reraise preflop, imo.

Raise bigger on the flop, and that's not even debatable. The pot is ~$14 and you raised $7 with multiple opponents.

Looks fine.

problems like this arise when you don't 3-bet this hand preflop. you have no clue where your at and your aggression seems to be coming out of left field.

as played i agree with zach that the raise is too small. noone is dumping any sort of hand or draw. make them draw at a bad price you know the name of the game.

Reraise preflop
LEAD THE FLOP!!!! after the original raiser checks. He's the only person that you should ever count on to do your betting for you unless there's some aggrodonk at the table.
Then everything Zach said.
