Well, it's easy to spot Indiana Jones whip unless that already existed from earlier sets. That must have existed beforehand?
Just to the bottom left of the whip is a grey T piece with what looks like a tin can attached. I had loads of those from my 80s space sets. I used them for detailing on spaceships or as a gun for the minifigs.
You've got so much there including classic castle stuff.
The whip is from the Indiana Jones temple set that included the completely round ball piece. It's one of the last sets that I picked up.
The sets range from the early 90s to late 2000s. Part of it is from my childhood and the rest is from an older sibling.
I see a shield, a flag, and an axe. Maybe some castle/medieval sets in there? Might be worth comparing to parts lists of castle sets from that era. Are these from before or after the 2004 light-grey colour debacle?
The flag, sword, axe and shield were all in a castle set I got for Christmas in the mid 80s! I presume they kept producing sets with them well after that though.
