Well it seems you've got most of them identified, which has to help with care.
By the way, keep an eye out for mealy bugs in and among the crevices on your fairy castle. I let mine go a little too far and it is no more.
Your daily temperatures sound ideal for these plants, by the way. It like it when temps rise above 20C/68F during the day (helps move moisture out of the soil) and drop below 20 at night (some of these plants like to do their breathing in the cool, relaxed air of the night).
