The answer is entirely dependant on the species to which you refer, and there are over 2000 known species of starfish to choose from.
Generally speaking the lifespan is longer in larger species. For example, Leptasterias hexactis reaches sexual maturity in two years, and lives for about ten years in total, while Pisaster ochraceus reaches maturity in five years, and may live to the age of 34.
Starfish have been known to live up to thirty five years. There is no known record breaking age of a starfish.
Depending upon the species, starfish can live between 10 to 34 years of age. Assuming they are not prematurely ended.

Starfish..Grow through a process called pylatithus
The starfish will regenerate another arm. The arm that was lost does not grow into another starfish.
as they get older they grow where parts get out of.
No, because all starfish do it.
A starfish can reproduce by mating with another starfish or asexually. Asexual reproduction is usually done after a starfish experiences dismemberment. The dismembered arm can grow into a whole new starfish.
