The first two appear to be some sort of Echinopsis, quite possibly a hybrid of some sort. You will probably get white or pink-tinted flowers from these. The third looks a bit like Trichocereus spachianus, although I'd need a closeup to be sure. Number four is Notocactus magnificus, and a nice specimen too. I'd love to see a pic of the daddy plant in the garden (hint hint!). Number five I think is Mammillaria microhelia. Photos six and seven are another Echinopsis, but again I'm unsure which one. Photo eight is a really nice clump of Rebutia... I get all confused about taxonomy here, so someone else may be better equipped to shed light on what it may be. And finally, the last one is Mammillaria vetula ssp. gracilis.
