What a great idea! Id love to contribute. Do you have a collection already? I know that most people would love to swap with you - are you after rare ones or just a general collection? Are you doing desert cactus or jungle (shady) ones? Email me and Ill let you know what Ive got at the moment. Cheers

Just generalities is all I can offer... The cactus looks like a Mammillaria, the middle looks like a beat up Kalanchoe thyrsiflora (Paddle Plant), and the right appears to be a Crassula of some sort. As Ken mentioned, the Cacti & Succulents Forum would give better detail. Here is a link that might be useful: C & S Forum

I bought this at Walmart and it had no name or directions on how to take care of it. Please help ;)
