Alas, I believe all three of these aren't genuine ancient coins. To me, they look like the typical "tourist fakes" you often see for sale in Turkey.
The middle one is definitely a fake - it's a copper copy of a silver tetradrachm or dekadrachm of Syracuse, a very famous coin design.
this old thread has a similarly fake dekadrachm, though of a slightly different design;
this other thread has a fantasy coin with the same obverse as this one.
The top one isn't Roman, but I'm not quite sure what it's supposed to be; I can;t see any writing or markings, which would be unusual for an ancient coin. It may be a fantasy issue like the one in the second thread I linked to above, with designs taken from coins from two different cities. The animal on the reverse is a goat; a standing goat like this was a popular feature on the silver coins of Ainos;
see the Wildwinds page here. The same "burnt orange" patination can be seen on both this coin and the middle one; this is not the natural colour for an ancient copper coin.
The bottom one is I feel the one most likely to be genuine, but if all three coins came from the same place, I'd be worried about it, too. The bee and the stag are both common design elements on the
coins of Ephesus, and plenty of different types of copper coins with both on them are known, like
this one.
