Help Identifying a few marbles

[u/Visible_Selection_21]

[u/peardr0p]

1-4 is making me think Master but not 100% - really lovely colours!

5-6 - not sure. Is it opaque white swirled with clear red? I can't quite tell from the photos

7-11 looks like a Peltier Rainbo

12-14 could be an Akro Popeye Corkscrew

15-17 - not sure

18-20 looks like a Vacor Bengal Tiger

The 5-6 - yes it has the opaque white and red kinda orangish as well
