Fake Or Genuine

to the community.

I agree they are all fake.

Welcome to the forum.

And sorry to concur with the others, but they all appear to be replicas of some kind.

The top one is indeed a replica of a Syracuse dekadrachm. Genuine examples don't have the huge wide rims like that, for starters.

#2 appears to be some kind of Romanesque medal. I assume it's rather large? The inscription is too fuzzy to read, but from what I can see the style of the lettering does not look authentic. It may be a copy of a "Paduan", a type of fake/fantasy silver coin made hundreds of years ago (original examples of which have now become collectable in their own right). So in that sense, it's a copy of a copy.

#3 appears to be inspired by Ptolemaic Egypt silver and bronze coins, though the artwork looks distinctly non-classical. Perhaps it was copied off of a line-drawing or picture, rather than an actual coin.

#4 is copied off of a "pith helmet" silver tetradrachm of Bactrian king Eukratides I. Clearly this coin isn't silver; it would probably qualify as a "tourist copy", the kind of thing you might find in the street-markets of Iran, Iraq or Afghanistan.
