Nothing seems very clear to me.

Here's a general rant.
PF - Seems fine.
Flop - Feels like top pair with a weaker kicker, 56 (if he's looser Post Flop than you expressed) or JJ are in his cold-calling range. Your description of him post-flop does not make it seem like he would RR with K10 (feels like he would just call).

This is very player/read/moment (that last few hands) dependent. If he has the capacity to put his chips in there with a worse 10, then you probably have odds to get in there.

Calling feels safe, but maybe too weak. If he's going to play this hand in an aggressive manner, then you would have gotten it AI on the turn anyways.

These feels kind of gross if he plays passive postflop, but we can't discount him making bad decisions.

If I were to put him on a hand, I would put him on JJ based upon his post-flop aggression.
