I think the darker red ones are what are known as "bricks" by collectors.
When that style was first introduced it was called American Cornelian.
It is a popular and not easy to find marble style.
With the different lighting, I think you have a vintage marble. In some ways it looks like a slag but some of the pictures hold me back.
I'm going to offer Akro slag as a tentative ID.
Hi. The blue and white one is a Marble King Rainbow. Could be 1960's or a little earlier.
The red and yellow and white one ... that has roughly the pattern of a Vitro All Red. Some possibility of being made by a different company, even Marble King. But usually I think those would be put in with the Vitros.
Do you see any seams/cutlines/poles?
I think I might see on peeking up from the bottom right in the first photo. A more centered view of such features could help.
How did you come by it? Or when? Did any other marbles come with it?
There are things about which make me think Jabo. And things which make me wish for more views ....
I remember a time when boxes of 1" (or thereabouts) Jabos were sent out from the factory with 1" Imperials mixed in.
I can't remember if we got an explanation of it or if I just assumed that Jabo had orders to fill and ran short and supplemented the orders with the Asian marbles.
Are you sure the others were Jabos?
I guess the modern ones I would think they most looked like would be the Vacor Old Fashion

The texture and brightness of the white on the first two, especially the red one, makes me lean toward "foreign" for them. Possibly modern, which would be Vacor.
But I'm not solid on that. Obviously.
Not a pontil. This is a machine-made marble.
There's a loop in the ribbons there, so it looks like the streaming glass folded onto itself once, and then didn't fully get rounded when the marble went down the rollers. Leaving the indentation.
I was trying to play it safe. I thought Navarre was one of Leighton's ventures, so I thought Leighton would cover it.
But I guess I don't remember any more. I've been trusting my memory too much and not double-checking -- which has led to quite a few mistakes in recent days.
