Could you ID these two Mammillarias?

Hi,
I am not sure about the identification, but I see that the second plant shown has a name of tesopacensis. That is a form of sonorensis, I think.
I think the first plant shown could in fact be a sonorensis form. Depending on what "authority" you follow, that could include some other names, like craigii and also tesopacensis.
Now the second plant could be a form of magnimamma, in which the spines can be extremely variable, but that long white lower spine, and just a few other spines suggests that to me.
However I'm always willing to be proved wrong! Its the only way I learn...
