I see the second seam a little better on the first marble and although the glass looks Akro, I'll agree with master for it. Good eye. Akro and Master used the same machine, so there can be and are some that are very difficult to tell apart. Usually the master seams are much smaller and more curved. I'm sure it's one or the other, not 100% on either. If you can get a macro shot of the seams I could tell for sure.
#2 is odd. I see bubbles in your new pics. I would rule out jabo for that one. Now that I can see the seams better, it looks like it was constructed in reverse of the norm... in other words: On marbles with this kind of moss agate glass, the base glass is usually the mossy glass and the patch is usually the color. It looks like this one had a red base and the patch is the moss agate color. I've never seen one like it. The cuts look sort of akro, as does the moss agate glass. If I was betting on it, I'd probably say Akro with much uncertainty.
The last is surely a pelt rainbo.
