Hello and welcome.

Quite a mix indeed. I'll be using a row-column ID system (eg. "R1P5" is first (top) row, fifth coin from the left.
Some of your coins are early Islamic: R1P3, R1P5, R2P4, and probably a couple others.
Some are Roman: R4P7 is the clearest, also R2P5, R4P3, R4P4 and R4P5.
Some are "Greek" - R1P4, R3P5 and R4P6. Also classifiable as "Greek" are some Nabatean coins: R2P1 is the clearest.
One at least is Byzantine (R1P2).
Some, unfortunately, are replicas/reproductions, or at least of very questionable authenticity: the triplets R3P1, R3P2 and R4P1 are not only suspiciously similar in appearance, but as far as I'm aware the design is only used on mediaeval Armenian silver coins. Three pairs of twins (R3P3/R4P2, R3P4/R3P5 and R5P1/R5P2) have the nasty combination of being too identical in design and strangely coloured; it makes me think they may be cast copies. R3P7 appears to show someone in a Native American headpiece; some kind of medal or fantasy coin.
Others such as R1P1, R1P5, R2P2, R2P7 and R5P3 I can't identify offhand; most of the remaining coins not yet mentioned have no visible markings at all in this pic.
Post some nice closeup pics of both sides, with just one or two coins per thread, for a chance at better ID - and so we can more easily move them to their appropriate locations once the ID is verified.
