Happy to help you out Dave! Glad to see you sticking with it!

The only one in that group I would call JABO is the green/orange one, 4th in the top row.

I'd go master, then two JABOs or Vacors. I can't zoom in and get enough clarity to be certain.

I'd stick with Master for the first, the second is a Vacor swirl. Notice it's not the same in any way other than color when compared to the MK bumblebees. Look at the construction and you can see the difference between a patch type marble and a swirl. MK wasn't in the swirl business. Last one also looks like a Vacor. Vacor makes both swirls and patches and other types too.

Yep, same here.

From these pics I'd call the first one Ravenswood. Then you have a brick normally attributed to Akro, and a red/white Alley, and the dark one looks like probably a Ravenswood of some sort, nice well lit clear pics of it and the first marble would be nice, the first is a good marble.

Yes, that is a known Kokomo type. Here's' one

First one yes, second one no.

Looks like a transitional.

Kokomo

The makers had sections the marbles rolled down. If the marble fell between the 1/2" track, it was a 1/2" or maybe reject, if it fell through the 5/8" track, it was a 5/8" marble even though it might have been a bit less. If it didn't, it would go to the 11/16 or 3/4" slot, whichever they had set up, and it would fall through it and be called that size. A .66 marble would have gone to the 11/16" or 3/4" track most likely. Some makers even used the ought system, like double ought (00), and so on. They weren't so precise as we are now with these calipers.

Akro to me.

Yes, St. Mary's Alleys.

Good example to compare with Chad. I agree, th OP doesn't look like mica.

If 5/8", I think possibly SMM A&B run for the first one. if 7/8" or more, then JABO. I think a pulled wonky Pelt for the second.

Alley.

Akro and PPP.

Agreed, pic #2 gave it away, Akro.

A nice example IMO, white or not. The dark green heavy coverage makes it better than many in my eyes. The smaller size is cool too, I think that in-between size might be harder to find than the 5/8" versions.

I would think Akro would be the most likely maker because of the seams, the pinkish streak, and the size all combined. Just a best guess.

They have no name that I know of. They've been called rainbos but I think they are NLRs personally. I really like them.

Yes you were. The second one not being an easy one to ID, so good job!
