#1 is some kind of patch -- possibly Akro.
Sticking with Master on #2
Glad I saw the first picture on #3 because I still think it's probably Peltier, but it sure has a weird fold in it.
Still in the general "West Virginia swirl" area on #4 and #5.
I think #6 might be a Master. Master or Akro.
#7 might be a Vitro.
