JJ from BB facing 2 villains

A 4bet could be a option as well to like $12 and fold on a 5bet jam. Without closing the action and no position it's really tough to play this hand with just calling I think.

As played I would just fold the turn. He's leading in 2 players and it would be tricky for him to bluff here and he has often top pair.

I also prefer cold 4betting, though when I do it I'm not folding to a 5bet (doesn't make sense).
Look at the UTG stats. He's a maniac with 86% f3bet and CO seems reg, so he will 3bet UTG open very light here. I'd be happy 4betting and calling a shove.
I'm not very happy OTT though. You block a decent amount of bluffs (QJs, JTs, J9s) and he's betting into 2 players. I'd fold right here unless you know something we don't.
He can still have strong Ax.

Heh, if you'd play this hand all-in preflop ten times, you'd loose 500 to the other guy.

May be calling the 3bet to attempt to see the flop is a valiant effort? And fold to a big 4bet preflop.
Folding Jacks preflop would give me nightmares....

4-bet/fold

This is a sick hand to play in BB cold-calling multiway.
If it is all low numbers, we may not be good.
If A or K shows, we may not be good.
And we are always out of position. Rather get the info I need pre-flop than playing a really tough hand post-flop out of position.

Also as pointed out since UTG is fishy with his stats, CO might be 3-betting lighter which gives us better FE with our 4-bet.

NL50 is a bit out of my reach by I agree with 4bet/fold in this situation. UTG is not our concern, we can go 4bet/shove against him. 3betting range of CO is gonna be much lighter in this spot than the stats suggest. We should have big enough fold equity against him, but if he jams I would just fold. So we should wanna isolate against the fish. I dont like playing JJ in a 3way pot OOP. If you were on BU, cold calling could be an option.

As played you can probably fold the turn already. It might seem weak but CO has many aces in his range (and I would expect him to go for this line check flop, bet turn on this flop) - AJ+, maybe even small suited aces. And he bets to two players in a 3bet pot. He might put you on hands like JJ-QQ and try to go for thin value. And I dont expect him to try to steal this pot since the UTG has all the aces in his range.
