A strong second possibility for #3 is Turbinicarpus pseudopectinatus. It is very, very similar to M. pectinifera.

By flower location: Turbinicarpus flowers grow from the tip of the stems. Flowers and buttons of M. pectinifera will appear in a ring around the stem.

This can be Mammillaria blossfeldiana or M. hutchisoniana.

Thank you for your explanations. I looked on Google Image, and I understand better now. I'll know when it blooms!

Got it, thanks a lot

Unfortunately differentiating species out of flower often comes down to comparing proper botanical descriptions rather than just looking at pictures. However few these days buy books containing such descriptions. One of the first things a collector should learn is how to read a proper botanical description.

Luckily you can often find descriptions and not just pictures on the Web if you search.
