Wow, you caught me out of practice for terms. Ok, I know them all, but can only remember the names of a few. I'll tell you how to care for them, but you may want to go to entheogen.com to the cactus forum for identification of the ones I don't remember.
The top picture has two I've owned before, but don't remember the names. The one on the right does better indoors with partial sunlight, watered once every two to four weeks (pull that strawflower off and throw it away, it's just hotglued on there).
I think the one on the left is a pilocereus, but i'm not certain; same care as most of the others, good when acclimated to full sun, water every 1-3 weeks during the summer, bring indoors and store in a dark cool closet for the winter unless you're just keeping it in a window.
pretty sure second pic is another variety of mammilaria, but I could be mistaken, treat like the other in the previous post (a lot of this will get redundant with the cacti)
Third pic is one of my favorite species, Old man of the Andes (oreocereus) and can be treated the same as the others. no nitrogen, acclimate to full sun and hot temps in the summer, bring indoors for the winter, water every 1-4 weeks, likes phosphorous a couple times a year.
Fourth pic is a common aloe (you know about those) and another variation of oreocereus.
Fifth pic left is a type of Crassulaceae, not sure of the variety. It's pretty stretched, likes partial to full sunlight (needs acclimation like jades) and water once or twice a week. weak mix of all purpose once or twice a year. right side is an ornamental aloe, treat the same as the first.
I don't remember the names of either of those in the last pic, but the succulent likes water, once or twice a week, easily rooted if you want to trim and make more in a bigger pot. The Cactus is not a mammilaria, but I don't remember the name atm. If i recall, I'll post back and let you know. You might want to check entheogen.com, cacus forum. those guys and girls know their stuff.
Hope this helps!
