OK, I'll try again.
#1 is M. stella-de-tacubaya, a species close to M. lasiacantha, but with a dark tipped hooked central spine. The central spine is rather variable, some plants have a really stout spine, others none, or very short. Your plant is in the latter category.
#2 is a Turbinicarpus, and I am not sure about the species, maybe pseudomacrochele.
#3 I don't immediately recognise, though there are several possibilities I have in mind. Do you have another photo? if possibly taken so it shows the whole plant body.
