You're on the money with your "MK p&r green and white" being Marble King.
Your "P&r (maybe) red-orange and white" are also Marble King patch and ribbons.
This style was called "Rainbow" by Marble King. With the basic white plus one other color they're not as valuable as the Bumble Bee or other styles with special names (such as Wasp, Tiger, Cub Scout, Girl Scout, Dragonfly, etc.) With the plain white the value is less than $1 apiece. The others I mentioned with the special names start getting a little pricier. I haven't seen those in your group though.
Your "P&r (maybe) blue and white" need another look.
Ah, now I see how the numbers work. The blues are #48, 22, 58, 71 and then #53 in photos by itself. Well, #71 appears to be Marble King P&R. The others I don't think so. #22 and 58 might be Akro patches. Specifically Akro Royals. I'm leaning Vitro for #53. #48 might be a more modern Marble King style. Not a traditional "patch and ribbon" pattern.
Well, those are my thoughts on the first three folders. I'll take a breather now.
