Photos 1, 4, 5, 6, 7, 8, 9, and 10 are surely of fakes (Photo 10 goes with 1). 2 and 3 are of a very worn coin with some corrosion. It is possibly Caracalla and surely from that approximate time period. That one looks genuine.
For Coin 10 & 1 I can show you what the fake looks like when it has not been through an attempt to artificially mask the fake. This image is from a database of known fakes and comes from the same die pair
