One is a trapezoid knife the other is a flake quick knife I don't know what the darker one is exactly but I do know they were tooled by the bulb marks and knapped edges more than 5 in a series isn't natural plus they fit very nicely in fingers
Looks like the type of stuff usually found at a quarry site.
Alot of reduction debris,some roughed out incomplete items and some expedient tools for use while camped out at the quarry.
That first thing looks like just a large reduction piece that got picked up..some chips taken off to use once then discarded.
