which is their name?

Hello
In the first place, thank you to help me to go up the pictures
I bought these three Mammillaria. Can you help me to identify ?







How many pixels, can have the picture?
I can go up pictures of my collection?

Thank you for your answer

My attempt at identification of the first two pictures: 1 M. polythele ssp. obconella. 2. M. geminispina

And I think that no 3 is also a form of geminispina, but a variegated one - or a bit sick

Chris and Amante
thank you for your answer. I ask to both the third it could be M. albilanata oxacana?.

I don't think so.
M. albilanata ssp. oaxacana usually develops wool at the apex and in the axils.
But I do know it is quite variable.
So I can't say yes or no, I'm afraid, I just feel it is unlikely.
