Salutations, Pauline!
That sounds like a respectable collection of cacti you have. I myself have never had any cacti until a week ago when they went on clearance at a local store (2 for a dollar 89 :|) )- I got myself a handfull of Christmas cacti (orange and red tops with losts of little babies coming out everywhere), and a handful of miscellaneous other cacti. I also recently made a cutting of a friends cacti- don't know what it is, but it consists entirely of long tendrils with fuzzies all over. So, I am somewhat excited by my new collection.
