The one on the left is a Star Cactus--Astrophytum ornatum, not to be confused with the grafted albino Gymnoclyciums sold by the same name. The middle one is one of the Club Chollas (Tephrocactus, maybe diadematus). The one on the right is a succulent Euphorbia rather than a cactus, probably in the E. horrida group, but the care is the same.
