@sgeneina, first welcome to CCF. Second, for us to help you better, it would be best to split these six coins into multiple threads (perhaps the bottom three could be grouped as they look similar). That way, we can take a much closer look with better pics. For example, your first one is most likely Byzantine, but without a close-up pic, it is hard to say much more. Thx!
