Of course these are from a movie or video. Nothing but fake cancels on the ones visible.
#1, #6 and #8 are the 1c Jefferson stamp from the mid-1960s. Probably all fakes since the stamps in #1 look like they have huge margins and no perforations.
#2 and #3 are fakes of the 1945 Texas statehood commemorative.
#7 looks like more of the 1c Jeffersons but all upside down.
Larger images would have been useful. Kinda hard to see from here in section GGG in the mezzanine:
