Lucy68 - I believe you may be correct on #4 -Adromischus cristatus, possibly on #3 - Heart Fern (still researching that plant), and perhaps #1- Haworthia cooperi (checking that plant out to compare with other pictures).
Tiffany - #5 - Echeveria nodulosa does look similar. I am thrown off by the "warts" or nodules on some of my plant's leaves. So not totally sure. #2 - Sedum hispanicum is a real possibility. I need to see more photos and maybe take more photos of mine for comparison. (My photos were blurry, so need to take sharper photos for better comparison.)
#6 has me stumped. Unless it is Lace Fern (Asparagus Setaceus). It looks a lot like the photo in this link:

Both of you have given me some good leads and possible IDs. I will do more research, before I close out this thread, just in case they aren't all ID'ed after I do additional research.
I ask that anyone else who may recognize my plants to please post either your agreement to Lucy and Tiffany's IDs or have another ID for me to check into.
