The M249 is typically fed from a belt... 100 round "nutsacks" and 200 round plastic drums are often used. It can also be magazine fed from STANAG 4179 magazines (the type used in the M16 and several other rifles). Those can be whatever capacity they're manufactured for, but 30 rounds is typical.
it depends what gun it is but usually there is 8 bullets in a semi-automatic pistol. with some there are only 7 bullets in the magazine but to achieve the maximum rounds the gun can carry the 7 shot mag is inserted, the pistol is cocked and the mag is removed, another bullet is inserted and the mag is again placed inside the gun.
The M249 Squad Automatic Weapon fires the same 5.56x45mm cartridge used by the M16 and M4.
The maximum effective range of the M249 light machine gun is 1,000 yards (910 meters).

usually 90 rounds (rifleman) but that can vary with a support gunner, usually armed with an M249 SAW. The support gunner carries either box magazines or two 200 round belts
The standard ammo belt for the M-249 SAW is 200 rounds- although belts can be linked together- in theory, the length of the belt is limitless. Well, limited by how many cartridges and links you HAVE.
Technically the PKM, since it is an AK-47 variant it fires a 7.62mm round while the M249 shoots a smaller 5.56mm round
700-1200 rpm.
In short the M249 is effective up to 1000 meters to cover an area target which the gun is designed to do.
