ID Help?

[Eskendereya]

I recently got these two babies and have no idea what they are. Any help would be appreciated, thank you!

The left one looks like a little 'Fairy Castles'. Or maybe a clump of them? They do form clumps but somehow this one is telling me you have a potful of seedlings.

The other is a Mammillaria. Or Coryphantha? I think Mammillaria, but I'm not coming up with a species name so maybe it is a Coryphantha.

It's kind of hard to see, but the one on the right has some spines that are dark at the tip & hooked. Thanks for the info

Can't see the hooked spines, but it might be M. schumannii.
