Will Turner continued to serve Port Royal as its only blacksmith, amassing quite a sum of money. Some he gave to the poor, some he gave to his son, and some he gave to his friend Jack. He lived a long and healthy life, finally dying of old age shortly after his son's promotion to Commander.
Commodore Norrington retired soon after the events of this story. He lived on a rather good pension until his death. He never married.
Captain Jack Sparrow got his rum and his kiss...on the cheek. He captained the Black Pearl for many more years, finally turning over command when he could no longer fulfil his duties. He retired to Tortuga and enjoyed the high life for a few years until his death.
Young Willy Turner went on to fulfil his love of the sea in a more...legal...profession: the Navy. Commissioned as a midshipman under Captain Gillette, he rose quickly through the ranks and eventually attained the rank of Commodore. He commanded a fleet of six ships, before his tragic death in a firing accident.
