Check the turn. Your bet is basically a bluff that is unlikely to work against 3 opponents, although wow at getting V1 of 56. A check/raise here would suck. Just check back, hit the 9
on the river and stack 78o.
As played, I think I can find a hero fold here. V2 has a king here a lot, and your kicker is now one of the worst. Your image does matter a bit, but I still think he has a big hand here most of the time.
As for limping, in general as stacks get deeper, we are going to want to raise more in position, not limp. At 100bb depth this is fine to play as a limp, but you can do more raising pre, especially OTB here.
