Hello everyone, I have had these guys for some months now and I am still unable to identify them with 100% certainty.

I think this first one could be a form of Cochemiea grahamii, previously known as Mammillaria grahamii.

This one, I have no idea lol but it is definitely not an M. zeilmanniana but something else...

And finally I think this one is a Mammillaria duoformis "Tenango Del Valle" but still not 100% certain. It has double red hooked spines on each areole.

I would greatly appreciate any input on what they could be

Not sure I can help. My M. grahamii is more rounded and covered with white spines. But I grow them hard. Maybe yours are more protected from the sun than my plants. Maybe you have to wait for the flowers.

The first might be a Cochemiea grahamii, they all have different spines even from one place. For the second I thought also about M. zeilmanniana (or Mammillaria nunezii, M. rekoi). Third reminds me M. tetrancistra or blossfeldiana.
