For the blue/green, here's an idea why I'm thinking Akro ...
A lot more Tri-Color pics showing range of variation:

Just put the cats on a piece of white paper and that would be a big help to me. Cameras will automatically gray the picture but with the white in the background that will be enough cues for my brain to see what it wants to see.
I don't remember there ever being solid evidence of marbles made in Canada, but it's intriguing how that transitional type is so often found there.
I'm on the fence about #1. #2 does lean more foreign for me. Would be good to see photos of both on a white background, to show off whatever tint the baseglass might have.
The third looks like one of those mystery transitionals which are mostly found in Canada ... which I guess some were hoping were made there.
I wouldn't say "likely". Mostly something about the crisp texture of the white which gives me pause. Has me wanting a little more input.
It's quite gorgeous -- such a perfectly round pattern -- which would lead me away from Asian, and could bring me back to MFC. But mostly I'd like to hear more discussion on that one.
2nd picture, 4th from the top, that looks least Pelty to me in the bunch.
I think they could have been sold as Bloodies even if they weren't opalescent or even translucent. But naturally there are some which modern collectors consider the ideal.
Could be Akro on top. I'm not feeling distinctly pelty feathering there.
My first thought was something non-USA or pre-MFC on the bottom. But I don't feel strongly about that.
The gap at the seam suggests possibly European.
I don't know much about their color ranges though. Christensen Agate would be the second choice.
First thought is Akro for the bottom. Would feel better seeing the seams.
If that's white on top of green, then maybe Japanese?
But if it's green ribbons which just cut deep, then maybe Peltier?
Do you see a cutline or a tail on the slag? If not, then for now I'd just have it in with generic slags.
