I see splattered lead, a buckle what looks like a button possibly toasted coppers ( at least they look like it to me) and maybe a button? Not sure about the rest. Those are some pretty neat finds dude!
Mentioning only the ones I think I can ID, from left to right in the "main" photo:
miscellaneous lead scraps,
fired post-civil-war pistol bullets,
a fired civil war Minie-ball, specific type unknown (needs cleaning and closeup photos), "mushroomed" by impact,
horsegear strap brass buckle,
odd-shaped brass button (need photo of the back to be more specific),
rivet from some kind of leather equipment (need to see its back),
brass eyelets from a poncho or tent or tarp.
