Top one looks like stone agate - bullseye type. Next one maybe Heaton or Alley. Next three are Peltier - Rainbo, Zebra (NLR) & Rainbo. Last one could be Peltier also.
Red & White looks like Master patch. Green cat's-eye - probable US made but? Single color ones are opaques or clearies - mostly used as game marbles like in Chinese Checkers. Cant quite tell on the regular size one - could be a Peltier.
Got some nice multitwist corkscrews including transparent purple base and root beer base plus some CA's - https://www.ebay.com/sch/arasmus/m.html?_ipg=50&_sop=12&_rdc=1
Others in general - not Jabos - could be an Alley or other West Virginia company swirl type or a Vitro, etc. There is a possibility that they are all Jabos since there are so many different variations to the classics and just seeing one view (or partial) view of the marble makes it hard to tell. For ecample, there is one to the left of center - white with a green ribbon outlined in darker color that could be other than Jabo. Nothing definitive.
Ignoring the left two, the middle is possibly a Japanese Wales type patch that is similar to a Vitro Conqueror. Lower left is MK Rainbow Red and upper right is basic game marble (made by many) in Chinese Checkers sets, etc.
I haven't seen Ro on this Board for years. Not sure how to catch him. He does have a page on Facebook but has not posted there for a couple years. Good luck in contacting him and with your glass blowing.
