Can You Help Me Identifying These Coins? | Fantasy / Replica

Strike me down if I'm wrong, but the first five look like fantasy "reproductions" to me.

middle two look like reproductions to me (does anyone else see casting on the edges?)
The bottom right looks legit to me.
What is the metal of them, put a magnet on them. We might be able to help you out more if we knew that.
The two on the right look like polished bronze with artificial patina... just my 2c

Where did you get them?

There are only three coins there. The pics in the top row match up with the pics in the bottom row. Nevertheless, I believe pls is sadly correct - all three coins are fantasies/reproductions. They're all supposed to be either silver or gold, for starters, and none of these look silver.

#1 on the left is a fantasy with designs taken from two different coins. The obverse legend is all mixed up, but appears to be a young emperor Caracalla. The reverse is taken from a gold coin of Maximianus, a much later emperor.

Coin #2 (in the middle) is a very bad copy of an ancient Greek tetradrachm or decadrachm of Syracuse; these coins are widely regarded as among the most beautiful in the ancient Greek series and are therefore widely copied. the angelic Victory overhead seems to have disappeared from yours entirely.

Coin #3 is a copy of a tetradrachm of the Seleucid king Demetrius I..
