maybe the first one is M.uncinata

The second one is probably a form of haageana.

Thanks mmartic maybe it is haageana ssp acultzingensis. Or chiapensis/yucatanensis?

A form of Mammillaria albilanata (tegelbergiana)?

The first one is M. uncinata (rigid centrals with a hook). The second one might not even be a mammillaria, but perhaps a parodia (notocactus). The flowers would reveal its generic identity.
