If it came from a flashlight, just connect it to a similar set of batteries.
(A switch and a case might be useful as well.)

Start with a single AA and work your way up...

Do not post multiple topics for the same things, it's pointless and clogs up the forums.
A 5W LED will likely need a heatsink, on top of that it'll need a power source. Depending on it's forward voltage and current limitations. Any info about the original flash light would be handy - batteries it took and any additional circuitry.
