Hey im fairly new to the cactus hobby myself so I prob wont be of much help but im 99% sure that #7 is Mammillaria plumosa and #3 isnt a cactus its a succulent a "baby toes" or F. rhopalophylla
also its prob just me but it looks like you have all your cacti in peat or something similar that holds alot of water and sometimes u could grow cacti in those types of soil depending ur growing conditions but most people prefer having them in something with more drainage to prevent rot

Thank you so much for your help. Yes I already have read about it and I will try to find a better soil for my cacti, I think they are doing fine right know because of the hot summer that's going on right know, but will take care of that soon

I have a hard time telling ferocactus glaucescense and echinocactus grusonii apart before they flower, how do you guys differentiate it?
