No 3 is easy, it is Mammillaria decipiens ssp. camptotricha.
No 2 might be a form of Mammillaria Formosa - it is very variable indeed.
No 1, with hook spines and white flowers - hmmmmm.....it doesn't look like one of the Stylothelae series, and the other plants with hook spines that look like this tend to have pink flowers. I shall think more about it, and hope someone else has a good idea!

No 1 reminds me to mamm. trichacantha (synonim or variation of nana ssp nana) but I'm only guessing !!!

I think you are right, mmartin, with the species for #1.

Having thought about for a good while, and checked various books, photos, my own plants etc., my best suggestion is M. vergelensis, which is a form of M. nana. It has quite tight spination, more so than many forms, and its flowers can be paler than the usual yellow of M. nana. I have one plant of M. tricacantha and that seems a bit more open than the plant shown. But that could just be my conditions. northern light levels.
When I blow up your photo, the plumose radial spines suddenly become obvious, which is a bit of a give away. I should have done that before!
