If you're thinking Fire Red is like Yellow Version it's not. It works just like Red Version; you only get one starter Pokemon and you trade with someone else to get the other two.
You can only get those starters by either cheating, or by migrating from FireRed, or LeafGreen.
Choose it as a starter Pokemon. You can't find wild starters in any game. As an alternative, you can get a Bulbasaur in one game and trade it to your other game.
You can never find the starters in the wild you can though find johto pokemon.
You cant find it in Firered only leafgreen.
Staryu is a water type Pokemon. In Pokemon FireRed, it is possible to find lots of Staryus in the Seafoam Islands.

No, you can't. You get the three starters from different people throughout Kanto.
