Change your Pokemon? I will answer this four ways...
1) Yes. You press start, and go to "Pokemon" then you select whoever is in front and say "Switch" then swap its position with another Pokemon in your party.
2) Yes. During battle, you may change by choosing the "PKMN" option, and picking a new Pokemon to send into battle.
3) Yes. At a PC, you may deposit a Pokemon from your party, and then withdraw a Pokemon from its box.
4) No. Once you pick your starter Pokemon you are stuck with that choice. You can ask a friend to trade Pokemon with you, if that is your desire.
no
No. The ONLY way to get Pokemon from Pokemon firered is migrating.Go to Pal Park once you have completed the game to migrate.

Celebi cannot be found in Pokemon FireRed. The only way to get Celebi in Pokemon FireRed is receiving it from an event distribution. These events are sadly no longer supported for Pokemon FireRed.
There is no way to 'up' your chances of finding a ShinyPokemon in any of the Versions.
The only way to obtain Magmar in Pokemon FireRed is to trade it from LeafGreen.
