Try a cheat or something. First way (Cheat): Go to SuperCheats.com And click GBA.
Then look for Pokemon Emerald. Click Pokemon Emerald once you find it. Then Click
"GameShark Codes". And then look for Celebi (May cost a master code) And there!
(Not saying second way cause second way is SOMETHING)
No you cannot catch Celebi in Pokemon Emerald.
if you have emerald or Pokemon migrate celebi and 5pokemons in pal park
you can't
trade it from Pokemon naranja(GBA)(DS)
Celebi cannot be caught in Pokemon Emerald by normal means. You'll need a cheating device such as a Gameshark or Action Replay to encounter one.
Celebi is not obtainable in any games, but is obtainable from the Colosseum Bonus Disc in Japan or form a Pokemon event distributing Celebi.
you can use gameshark code

I got my Celebi for Emerald from the Pokemon 10th Anniversary. You can only get it through Pokemon events, or cheat devices such as Action Replay.
The only game you can currently get Celebi in is Emerald version (until the Celebi event happens for HG/SS).
