Quarterback: Generally the person who passes the ball. He calls the cadance and tells the Center when to snap the ball. He is generally the offensive leader (if not the whole team-leader), and is brilliant with the offense as a whole. When the offense is about to run a play that'll lead to crap, he audibles to a better play to run.
Halfback: Runs the ball. He's generally small, quick, and agile. Although can also be large and strong. He's usually either the most elusive or the most powerful runner on the team, and he has the second-best field vision (next to the quarterback). When the quarterback is having a bad day, or the pass defense of the other team is good, you generally let your running back run the ball and pull the load. He carries the ball better than everyone else on the team, and he generally gets tackled the most. He takes hits the best most of the time too.
Fullback: Doesn't get what you would call "great" playing time. He generally comes in with the halfback in any two-back sets, and usually serves as an impact blocker. In the rare occasion that he runs the ball, it usually for short yardage or on the goalline. On pass plays, if he's not serving as the man who picks up the blitz or is providing extra pass blocking, he normally runs a flare or into the flats.
Offensive Lineman: The people who make the holes for the runningbacks and block for the quarterback. They do the dirty work and don't have the longest of careers. Naturally the biggest men on the field. A NFL O-Lineman under 300lbs is considered small.
Center: An offensive lineman who snaps the ball. He has the most difficult job of the offensive linemen.
Wide Receiver: Runs routes, usually downfield. They're usually featherlite and very fast, and have soft hands that allow them to catch the ball. They're meant to be the fastest and most agile people on the field, as they usually can leap more than three feet.
Tight End: The hybrid between a receiver and offensive lineman. He usually runs simple routes, and is a safe bet for usually breaking the first tackle.
Devensive End: Keeps outside contain, normally is the fastest defensive lineman and is the main pass rusher.
Defensive Tackle: The big uglies on the D-Line. Incredibly big and strong, normally the main runstoppers.
Middle Linebacker: Usually the hardest hitter on the defense. They are used in blitzes to stop the run, and are brutal and relentless. They usaually cover the tight ends and backs in man coverage and play over the middle in zone. If he gets his hands on the unsuspecting fast moving player, they are toast.
Outside Linebackers: They play outside pass coverage and cover the backs and tight end in man coverage. They are quicker, lighter hitting linebackers who bring the outside pressure on the blitz, normally pass blitzes.
Cornerbacks: Very fast, smallest devensive guys. They cover the the receivers generally. When they come on the blitz its either a long gain for the offense or a long loss. Basically they're receivers with harder hands and stronger legs.
Strong Safety: A hard hitting corner that's slower. A fast linebacker that couldn't hit hard enough.
Free safety: A faster, softer hitting strong safety. An outside linebacker that couldn't hit hard enough.

Quarterback: Takes the ball from the center and then either hands it off to the running back, throws it to a receiver, or runs with it himself.
Runningback: Runs the ball. Lines up behind the quarterback for the most part.
Fullback: Blocks for the runningback
Wide Receiver: Lines up the furthest away from the quarterback and runs routes to catch the ball.
Tight End: Plays next to the offensive tackle. Blocks and goes out for passes.
Offensive Line: Blocks so the quarterback doesn't get tackled.
Offense:
Quarterback (QB) is assigined the task of deciding which teammate gets the honor of catching the ball and moving it up the field. Wide Recievers (WR) catch the ball and try to advance it upfield. Running backs (RB) get the ball handed off to them and try to advance it upfield. Offensive linemen (OL) and Fullbacks (FB) block the deffensive player for the QB and RB.
Defense:
Defensive Linmen (DL) try to get through the OL and tackle the QB or the RB in behind the line of scimmage (called a Sack). Line backers (LB) and Defensive backs (DB(or more specifically Cornerbacks (CB) and Safties (SS or FS)) try to knock down the QB's throw to a WR.
In short Defense tries to stop the Offense form advancing the ball upfield and scoring.
In typical american football:
OFFENSE- 11 players.
(Must have: QB, 5 Lineman, and any combination of 5 WR, TE, RB)
Quarterback, Running Back(s), Wide Receiver(s), Tight End(s), Full Back, Offensive Tackles, Guards, Center
(Depending on the formation, different combinations of these positions can be used. Some positions have multiple names. Ex. Running Back is sometimes called Tailback or Halfback.)
DEFENSE- 11 players.
(Any combination of positions.)
Defensive Ends, Defensive Tackles, Nose Tackle, Linebackers (Inside, Outside, Middle, Weak-side, Strong-side), Cornerbacks (Nickelback, Dimeback), Safeties (Free, Strong)
(Same as offense, multiple combinations of these positions can be used, depending on the formation.)
SPECIAL TEAMS- (11 players.)
Kicker, Punter, Kick Returner, Punt Returner, Long Snapper, Gunner, Holder
Example:
The center on a punt or field goal attempt is called a long snapper.
The person who holds the ball for the field goal kicker is called the holder, technically he is the quarterback for that play.
The wide receivers in a punt formation are called gunners, they try to tackle the punt returner.
