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.
I am listing a few duplicate marbles books and some magazines with marble related covers or articles this evening on eBay. Might be something that you are looking for. Will also be listing some marbles soon, probably over the weekend. Thanks for looking.

Top pic looks like cat's-eyes - hard to tell which maker from one view. 2nd pic from bottom, left one (green w-yellow stripes) fits in the Imperial packaged type (made in Far East) - newer.
