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.
