Central Mexico Cacti IDs

I think I have identified the one in the left as Coryphanta ottonis, although I am not certain of the species as it could be in the Mammillaria genus. I think I have identified the one in center as Coryphanta cornifera.

For the one on the right, the closest species I came across was a mature Mammillaria compressa, but that might be a far reach.

Any input?

If these were collected from the wild, from what locations did they originate?

The Coryphantha (center of the 1st image), will be easier to ID with a known origin.

The others appear to be forms of Mammillaria magnimamma

I purchased the three from a nursery in Leon, Guanajuato. However, I left them at a relative house since I couldn’t bring them back the US without proper paperwork.
