The first two are obviously from THOR issues, circa 1965-1968, I can clarify which issues later, or I'll let someone else answer that.
The third is the above one from FF ANNUAL 6.
The 4th is from FF 62, posted a few posts above (but here's a link to the full story).
The 5th is from JIMMY OLSEN 141, Sept 1971.
The 6th is from JIMMY OLSEN 137, April 1971.
The 7th and last is from Kirby's HUNGER DOGS graphic novel, in 1985.
