musket Or miguelet / miquelet.
Carbine, rifle, firearm, or gun. Those are synonyms for musket.

bayonet
Rifle.
No, a rifle has rifling in its barrel (spiral grooves to make the bullet spin, thus stabilizing it and improving accuracy). A musket barrel is smooth.
A bayonet is a thrusting weapon placed on the muzzle of a musket or rifle which turns the weapon into a spear.
