I'll go with my guess and TJT's confirmation. @:-)
"How many passengers can I book in one reservation?
You can book up to 6 passengers in one reservation on aa.com. For groups of 10 or more, contact Group & Meeting Travel. Special fares and discounts for group travel are available."
A Passenger Name Record may have a number of tickets - if one is altered it will get its own PNR. A PNR is basically a "handle" for a specific itinerary. And a PNR will eventually re Yale and get assigned to a new itinerary.
"In the airline and travel industries, a passenger name record (PNR) is a record in the database of a computer reservation system (CRS) that contains the itinerary for a passenger, or a group of passengers travelling together."

Tickets are discrete and unique; a ticket number will never recycle. And of course one can cancel a ticket.

If a PNR is generated for three passengers and one doesn't show, the PNR will continue to exist, but as others have explained the ticket(s) for the no show (or canceling passenger) will be canceled or invalidated.
