This belongs in the black-powder and muzzle loading forum. A mod will probably be by shortly to move it for you.

As for the guns.... I am not expert on them, but here is what I know.
Both of those rifles are fired using a percussion cap. A musket is muzzle loading fire arm without rifling.
The top pic of your second post MIGHT be Civil War. It is a Springfield (the main arm of those days). The plate that with the lock on it appears to have an eagle on it. I believe that symbol was used by the military gun ordinance around the Civil War.
As I said, I do not know much. Someone who is more qualified than me could probably tell you which states they have been in due to a scratch there or a spec of dust here. lol
