I actually think V1's range is stronger given that he check-raised with 2 villains in the pot. I think he may have either a better made straight (since this is a limped pot he can have anything) or some monster draw like clubs with the 9
.
V2 is most likely drawing. Club draws are probably more likely than straight draws. If he has a club draw then if he hits it we are beat.
I may actually be slightly behind V1s range
