H1) His raising range is probably Ax, flush draws and air. Your hand has little equity since his range has 9 outs minimum or is already ahead so calling his raise is bad. Turns will be hard to play as well

3betting as a bluff doesn't work because all better hands (and fd's) are calling due to your sizing and he may jam air some % for the same reason.

H2) Slightly bigger turn bet, river seems too thin without better reads. I like check/decide.

H3) Looks good, bet flop/check turn/bet good rivers is ok as well.
