As already said raise the flop.
You didnt so you might get pretty loose calls on the river because noone showed much strength postflop. Board was very drawy but the draws didnt hit. HJ should have bet a K in second-lastposition because he could not be sure at all you would bet. K and Q are pretty scary but it doesnt seem THAT likely from the action that they are out.
I think you should valuebet here. Some of the time you will lose one bet against a weak Q but more often you will win 1 or 2 bets against a 7 or other crying calls. As they are loose-passive you can easily fold to a raise.
