Migrate it(Nationaldex needed)First you will need Emerald.Then catch celibi on Emarald and then migrate using palpark.

I'm afraid you cant directly get celabi on Ppt, but you could trade for it on the gts or import it from a game which has it.
not catch but by Pokemon transfer or the Dreamworld
You cant without cheating
You cant,you have to cheat or trade it from another game
You Can Not Catch Celabi In Pokemon Firered Unless you trade with pokemon heartgold or soulsilver.

No because , the unova region has different qualities and settings. so you can only catch unova pokemon. but there is a cheat to get celabi to unova.
You can either get Celebi by using a cheat code or you can trade it from Pokemon Crystal after completing the GS Ball event.
