Shiny can be really good shape. Most of these look vintage.
#1. Can't guess with that view.
#2. LIkely Master
#3. I think this one will turn out to be a Peltier Rainbo.
#4 and #5. These may turn out to be a West Virginia swirls.
#6. I can't really guess a maker with that view, but I'm pretty sure it is vintage.
#7. No guess
For marbles which have cutlines and seams such as #2, #3, probably #4 and #5 and maybe #6, it's helpful to show those lines/seams. You show it clearly in #2. We used to have a tutorial to show how to locate those seams. I accidentally deleted it. I need to make another one. Making a big reminder to put beside my desk right now.
