I don't belive you can.
Go to the house next to the Poke Mart in Eterna City. Talk to the old man and he will change your pokemon's nickname. Sadly, you cannot change the name of trade pokemon.
Yes you can trade leafgreen version Pokemon to another leafgreen version.
Some people say to nickname your starter Pokemon "Mew" and it will play as mew for the rest of the game but I never tested it...
You can go to the name rater in Lavender.
The Name Rater in a house in Lavender Town can change your non-traded Pokemon's nickname.
Yeah, go to the name rateor
when you first catch a Pokemon you can give it a nickname but if you want to change its nickname then you need to go to slateport city and talk to the nickname rater (he will change the name of any of you Pokemon that are in your party)
I don't belive you can.

You cannot naturally change your Pokémon gender in Pokémon LeafGreen, you will need to such a cheating device such as a GameShark or an Action Replay in order to accomplish this.
