Looks like several of these will be easy to identify. I see an Urbs Roma, a BEATA TRANQUILLITAS, etc. But it's very difficult to look at a dozen coins spread out over several pix offsite and make any helpful comments. (Plus, my PC won't open the Imgur site, by my phone will.) I think you'd get a better response if you posted them one or two at a time in separate threads, cropped to the obverse and reverse. Maybe start with the ones you're most curious about, or having trouble identifying.
Top coin at the imgur site is unclear to me. Maybe Greek. Second coin might be a Constans votive. Third coin looks to be an Urbs Roma commemorative. 4th is Byzantine. 5th looks to be a Constantius II fallen horseman reverse. Then a Constantine Beata Tranquillitas. I'll let others look at the rest. But again, I'd post them one or two at a time.
