Any reads on the villains?

With no reads, I fold and wait for a better spot. While its possible that V1 has an overpair to the board and puts you on AK (they always do!), seems likely that V2 has you beat.

Why the less than 1/3 psb on the flop?

Easy fold to the raise. You have under played your hand, but it will be rare that your not beat by at least one of these villains. It would be never, but your underbet on the flop and check turn opens you up to bluffs or value betting by worse hands. Still, on the double paired board the bet/raise indicates strength.

Flop bet should have been $125/$150.

V1 was new to the table and v2 (button) was fairly lose

I would lead $110 - $160 here on the flop depending what I think of the players. This is for fat value against pretty much their entire range. You should feel 100% comfortable stacking off vs V2 here on the flop (and really, on the turn also if you make a proper bet size.)
You should feel pretty comfortable stacking off here vs V1 also given that you have an SPR of ~5.3 on the flop (if you make a proper sized bet on the flop).

If you bet $145 on the flop, V1 flats, V2 likely shoves, and I might just shove over the top of him denying V1 the right price to call with his flush draws.
As played it's a pretty easy fold given that we gave 7X a good price to stick around in the hand. If we bet bigger on the flop though, there are a lot less 7X type hands in his range and we can continue to bet on the turn, (or check/call is also possible, but not really idea I think) and know that his range has more draws and over pairs in it so we are still way ahead of.

I had v1 on a pocket pair (even though he was new to table) so the $60 could have some what been considered a check raise type of play. Looked for him to raise me back and then shove the flop regardless of v2's play. The call call from v1 and v2 was the scenario I hoped would not happen.

The flop bet is way too small. Lead out $120-$150. Call any shoves. As played fold and wait for better. Against two players, showing strength you are almost certainly behind.

The check/raise flop play can work, particularly against a loose opponent. However, usually you have to do the checking part first Too often when you bet weak your villain will simply call, looking to catch up or float you. Betting weak and looking for the villain to pick up on your weakness to raise you, so that then you can execute your bet weak/raise strategy will get overlooked by 95% of LLSNL players.
