I've done some research on the plant in the third picture and I believe it's a cynanchum insigne. I'm going to the California Cactus Center in Pasadena later this week & I'll bring a picture or cutting with me. They know EVERYTHING about succulents there! They've got a cyphostemma juttae there that has been consistently winning first place at the Inter City Cactus & Succulent show since, like 1978. Amazing nursery!
