The first two and the last one look like obsidian to me but I’m not the best at id’s. I’m sure others will be more helpful.

They aren’t obsidian though, they have a metallic luster and are very dense. I’ve got quite a bit of obsidian and this is a much different material.

Most look like metal slag. You can see where bubbles had formed in some of them. The orangish one is possobly phyllite, which has a very fine grained metallic luster from compressed tiny mica grains.

You really need to give more basic starting with the locality found. The more specific the better. For rocks like these streak, hardness and density are really a must as well. vegasjames may very well be correct with what he sees, I personally don't see bubbles, but I also cant really see good surface details since the images cannot be zoomed in on.

There is a magnifier function on the computer that you can use to zoom on on the pics. In the first pic you will see a small round impressions from bubbles at the top center, near the top left and on the top right edge. Bubbles in the second photo can be seen in the right center edge and just below the right center close to the edge.

Justin Images 1,2 & 8 appear to be the same material. From the image I do not see a metallic luster. I see vitreous luster. That is not to say in real life it may be metallic just I do not get that from the image. Hardness info might help, is it translucent? Images 3,4,5 are some type of furnace slag. I have seen this material before. Images 6 & 7 look like a schist with mica. Hardness here and do the shiny bits flake off?
