Oxblood should look like the oxblood on the Akros you have posted in a few other posts. You should use those to help you id other oxblood. If it doesn't match, it is probably a red or brown
I would probably go marble king for 1,4,5 and 6. 2 and 3 could be vitro. A few more angles would be good. Shots of the seams are always more helpful than the poles
I see a transparent base with a blue patch? That would be vitro. I would recommend taking pictures on a different surface. That clear display thing(forget what its called lol) is distorting your pictures
Lots of nice marbles. Condition would play a big factor in terms of value. I see a few that would have had some value if they weren't so rough. Definitely worth the time to learn what you have before selling
