Flowering. I think they are both Mammillaria. Anyone can ID?

First Mammillaria microhelia:_

Thanks, DaveW, for the ID.
The second cactus has some fish hook, is it possible to be a Mammillaria grahamii or dioica?

[DaveW]

I think it is probably one of the Mammillaria duwei/nana group which is very variable as to amount of hair and also central spine colour. It is certainly not one of the Baja California Mamm's you mention.:-
