These are just wild guesses, no guarantee to accuracy.
1) On one of the roads into the valley. Might that be a sign of some kind on the tree on the left? Cars and Trucks parked behind the tree on the left. Stables/Barn/Corral in the background. Not in the valley?
2) Swimming Pool? The Lodge, Curry? What cliff might be in the background? Does that look like the cliffs NW of the Lodge, i.e. the pool is at the Lodge?
3) This HAS to be somewhere at Happy Isles.
4) Ranger Station? At one of the entrance gates? Is that a message board behind the two guys? Are they talking to someone inside the door, or are they around something beside the door?
5) Nice! I'd guess Mirror Lake, although it might be somewhere along the river in the valley. I wonder if that rock is still there or if one of the floods since has moved it. Try flipping and mirroring the photo to see what the cliffs reflected in the water look like. MIght that be Indian Canyon reflected? If so then this isn't Mirror Lake. If that's Indian Canyon then this is late summer when the river flow is next to nothing.
6) My first impression is Glacier Point with the Geology hut in the background, but the hut is of rock and that building is wooden. Where might there be a structure on top of a dome? Or is it not a dome but just slabs going down from somewhere. Are there any other photos you can associate with this one that might give you some context? Why is there snow in just this photo? Different trip, or just a higher elevation?
7) no idea, not enough to ID, I want to say some around Liberty Cap or Mt Broadrick
8) Illilouette Fall taken from quite a ways up the canyon, someone did some real scrambling!
These are just a few of what you have? Was there more one trip? Are you sure they're all Yosemite related? It might be interesting to take your collection as a whole and try to match photos together by trip, roll of film, location, etc. You might be able to decern some interesting information that way.
