1/2 NL
Hero: (200)
V1: (100) On the Button
V2: (200) In the CO

I limp with 44 in LP; 5 way to the flop : 384

Checked to me and I lead 7 into 12; V2 calls; V1 raises to 21;

Back to me and I make it 37 more, I think I should be sizing up here looking back on it to give the draws a bad price to continuel

As played, prolly size up as somebody already called your flop bet. I feel making it like 45-65 is solid and leads to a turn that you can bet pretty big when it blanks like a high card.

I say make it 50. If two callers pot is what a tad under 160 and one caller is 110. This sets up for an easy big turn bet that could be called by a draw maybe.

As played, raising pre is prolly something you should consider. If you bump it up to 10-14, you have a bigger pot and can bet much bigger and still get called. I feel limping pre is kinda bad as it’s hard to bloat pot on flop. If you make it 12 and get 4 callers, pot is 48. You can lead for 30-40 and have a much easier turn plop. If you get 1-2 callers you still can lead flop in an easier manner against lees opponents.

I think that raise size is pretty good given V1 is short. No need to size up as that size may be enticing to V2's FD and they're not getting correct odds given you can boat up. If V1 hand a full stack I'd probably look to make it $65-$70 total or so.
