I'm not going to look at all of those, because chances are we've already vetted them.
The ones that we have available, are here:
So if your copy differs from these, not the real deal.
As for Slowpoke, Shellder and Sandshrew, I would take another look at them.
Tho chances are, they are not the real deal. Jeremy's mon are all in-game mons, and to simplify the technical aspects, they have certain characteristics that one can tell that the copies in circulation were hacked. It's possible those 3 are of a similar situation, since we've browsed the net for such files.
Edit: We've seen this Sandshrew and Slowpoke before, they were dismissed as fake. Looking into Shellder again.
Edit2: What's the original link for your Shellder?
