Caliber refers to the diameter of a bullet (bullet is the part of a cartridge that is fired out of the gun). A .223 caliber bullet is .223 inches across. It is normally used as a rifle cartridge. a .45 caliber bullet is more than twice as wide as a .223, and is usually used in pistols. The .223 is lighter- it weighs about 1/4 of a .45 bullet, and they are different shapes- .223 is usually pointed, the .45 is rounded.
The .22 Long Rifle is a rimfire, whereas the .223 Remington is a centerfire cartridge. The .223 uses a longer 'spitzer' projectile vs. the rounded projectile of the .22 LR. The .223 tends to be a heavier projectile, and has a much higher velocity than the .22 LR.
The M16 assault rifle is chambered for the 5.56x45mm NATOintermediate rifle cartridge. It can also accept .223 Remington rounds.

Not without modification. Some 5.56x45 and .223 Remington rifles have a device available for them which allows them to fire .22 Long Rifle rounds... typically, the device replaces the bolt carrier group.
Depends on the Caliber and grain of bullet. You can shoot a .22 m4 accurately probably 100-150 yards. Then with the 5.56/.223 round can be shot 600-659 yards accurately.
