I think the middle row green one with the oval and arrow is Malachite. The black one obsidian?
The one next to the malachite is white with gold flecks and quartz.  Thanks for the help.

I tried to zoom in, but the photo doesn't have a high enough dpi to show detail. The lighter green on on the left looks like chrysoprase, of the lemon variety. The black is almost definitely obsidian, but I don't see any banding on the one you think is malachite, but not all malachite has it.

The white one might have pyrite or marcasite in it. The green on the lower right looks interesting, but needs a higher resolution picture.

The white one looks kind of like Calico agate from Mexico...

Thanks all Talisman I think you are right. I checked and it does look like Calico Agate.  Debbie I will try to get some better pictures. I do think the black is Obsidian. The one I think is Malichite u actually can see the banding if I show the edges. I will try to post some better pictures tomorrow. Thanks All.
