You have some lovely pieces there! Hopefully we can get you some answers.
I can take a stab at a few.
#1 looks like what's known as a selenite rose or "desert rose selenite".
#3 probably sodalite, but could be lapis. A close up would probably help so that those who are good at differentiating between the two can get a better look.
#4 is actually also probably sodalite--it's not as common to see it in white with blue as the blue is what's prized. I have one like that too though, and while I'm lousy at sensing energies, that particular stone called out to me from a 2 pound lot of stones, most much prettier, and I carried it around for quite a while after. It now lives on my nightstand, and is one I pick up for calming or stress. So for what that's worth, it seems to carry the same traits as the more popular pieces.
#6 *might* be amethyst, I've seen a couple of tumbles like that, but it's such a bright purple with such solid looking white that I kind of wonder.
If you have larger images of your crystals, I'd suggest posting them. In a lot of cases, two kinds of stones may look very much alike in a small lower resolution picture.
Good luck with ID'ing all of these!
