Kennesaw Mtn. Civil War Relics

The pictures are pretty fuzzy but here are my guesses:

The larger piece appears to be part of a Colt 1849 model eagle powder flask.

On the left are 3 Minnie balls looks like 2 drops and one fired and impacted.
One is a standard 3 ring Minnie.
The ball with no rings is curious and might be a bullet for a confederate Enfield.

The two items on the left are too fuzzy to warrant a guess.
