The AR 15 is a semi automatic firearm- it fires one shot with one pull of the trigger. It can fire as fast as you can pull the trigger. However, that will NOT be accurate, aimed fire.
"Armalite rifle" is a term used to describe two rifles developed for the Armalite Division of the Fairchild Aircraft Company - the AR-15, and the AR-18. The AR-15 was developed from the earlier AR-10. The AR-15 and AR-18 were both designed by Eugene Stoner.

Armalite rifle. Don’t listen to that idiot who said autolite rifle
"AR" was a shortened form of "Armalite" - the company which designed the AR-15, AR-18, and other firearms.
Similar. They are both "AR style" rifles. AR-15 is a copyrighted brand name- other companies can make rifles in that style, but cannot legally call them AR-15s. The R-15 is the Remington version. The AR-15 was developed by the ArmaLite Company- and AR actually stands for "ArmaLite Rifle".
This is not a car and its definition is not related to cars either. CAR-15 (Colt Assault Rifle-15) is a familiy of M-16 and AR-15 rifles. Part of this family is the ArmaLite 15, better known as AR-15.
The AR 15 was designed in 1957 by Eugene Stoner. The original manufacturer of the AR 15 was ArmaLite, but they sold the rights to Colt's Manufacturing Company in 1959.
The "AR" in AR-15 stands for "ArmaLite Rifle," named after the company ArmaLite, which developed the firearm in the late 1950s. It does not stand for "assault rifle" or "automatic rifle." The design was intended for use by the U.S. military, but it has since become popular for civilian use in various contexts.
The nature of this question makes it difficult to determine what you are asking, so I'm going to throw a few answers at you to hopefully answer it. AR in the firearms world is the initialism of ArmaLite, the company that employed the inventor of the AR-15 design, Eugene Stoner. Technically one could call any firearm built by the Armalite company an AR. However, the AR-15 and its derivatives are extremely common firearms and the design has been copied by many companies. Rifles built in the pattern of the AR-15 (and the earlier AR-10) are often referred to as "AR's" as a catchall term for that design family.
The lower is polymer, and the grip is part of the lower, so the answer is no.
