I'm no expert on E-bodies, but I recognize a few of those items from A & B cars:
U-shaped clip holds headliner to body flange
Nut with wedge-shaped (or cone-shaped) washer, machine thread for trim such as '68 RR trunk Decor panel
Stamped nuts at left also used on Duster sharktooth grilles
Window-roller clip & bumpers as previously identified
Roll pins always seem to go where they're a PITA to deal with
Shallow (stamped?) nut bottom right could be for accy lamp or even radio depending on size/thread
