If I use the Ways of Punishment on the First copy of a multiple card, would my turn end at the resulotion of that copy or would I continue to resolve the other mulitples in my card pool?

Any Help is appreciated

The wording on TWOP says that after your attack resolves your combat phase ends, and as multiple copies are seperate attacks, you would not get to resolve them.

If it had said your combat phase ends after this form resolves, that would have been different, since multiple copies are part of the original form, so you could resolve all of them.
