Espeon and Umbreon cannot be obtained in Leafgreen because no in game clock feature exists so you will need to trade one from a game that does feature this like Ruby and Sapphire.
You can't.
All starters, including Bulbasaur, can't be caught in Pokemon LeafGreen.
If you trade Pokemon between leafgreen and ruby ruby will have your leafgreen Pokemon and leafgreen will have the ruby Pokemon both in the party they will not be sent to the PC unless you personally walk to the PC and do so.

If you mean Espion (the psychic eeveelution) then find in Eevee in the Pokemon Mansion Trophy Garden and level it up when it's friendship is high enough between 8am and 4pm, it will then evolve into Espion. There is no Pokemon called Elspon sooo lol
you should go to gamestop
to get an espion you have to give your eevee alot of love and care. The man dr footstep will tell you how much you Pokemon likes you. when it likes you ALOT go and level up your eevee. To get sn espion you must lv up in day and to get umbreon you must lv up at night
