Hi there.
#1 _might_ be Peltier. Also might be Marble King. Need a better idea of how many ribbons there are and how they connect at the seams.
#2 is tricky. I'll go Master or Imperial.
#3, the first view looks to have a nice tail in it. So I'm figuring the 2nd view is a "nine", rather than a turkey head. I'm going to say M.F. Christensen slag, rather than Christensen Agate.
#4. In spite of your sureness that this was with an old group, it looks totally Jabo to me.
#5. So that red ribbon corks around the marble? More views could help but I'm leaning Akro for now based on the peek at the seam in the first view.
