In any Generation you can obtain as many eevees as you want by breeding one with a ditto. If you mean how many evolutions/forms of eevee there are, that depends on the generation of the Game:
1. Flareon (fire) - use a firestone
2. vaporeon (water) - use a waterstone
3. Jolteon (electric) - use a thunderstone
4. espeon (psychic) - friendship evolution (max it's happiness) during am hours
5. Umbreon (dark) - friendship evolution (max it's happiness) during pm hours
6. Leafeon (grass) - level up near mossy rock
7. Glaceon (ice) - level up near icy rock
Seven.
Eevee evolves INTO Vaporeon using a Water stone.
Eevee evolves INTO Flareon using a Fire stone.
Eevee evolves INTO Jolteon using a Thunder stone.
Eevee evolves INTO Espeon when it reaches full happiness in the Daytime
Eevee evolves INTO Umbreon when it reaches full happiness in the Nighttime
Eevee evolves INTO Leafeon near the rock in Eterna Forest
Eevee evolves INTO Glaceon near the rock in Route 217
There are seven total evolutions of Eevee: Jolteon, Vaporeon, Flareon, Espeon, Umbreon, Glaceon and Leafeon. However, Due to the lack of Moss Rock and Ice Rock locations, only the first five are available in-game. In order to get Glaceon or Leafeon, they must be traded from Diamond, Platinum or Pearl
It depends when eevee will evolve. Eevee can evolve at any level if you use one of the stones (fire, water and thunder) or, you have to use eevee in battles so it becomes freindlier (use soothe bell as it will help it work faster). My guess that eevee will evolve around 35-50.
You have to make Eevee really happy while it's is evolving,there is no certain level that will make Eevee evolve.
In Pokémon Platinum, the Thunderstone will work on only Pikachu and Eevee. Using the Thunderstone on Pikachu will allow any Pikachu to evolve into a Raichu and using it on Eevee will allow you to evolve into Jolteon.
To get Jolteon, you must first catch an Eevee, and then evolve it with a thunderstone. Go to your back, go to items, select thunderstone, click use, then click your eevee. Eevee must be in your party if you wish to evolve it :)
Evolve Eevee during the day
Eevee can not evolve into porygon.
No, Eevee does not have to evolve to breed.
eevee can only evolve once but if you get another eevee (of different gender )and breed with it you can get another eevee and evolve it into something else.
you cant evolve eevee into glaceon.
if i get eevee in level 20 what level eevee need to evolve into espeon
No, Eevee does not evolve with a Shiny Stone. Only Togetic, Roselia, and Chillarmy evolve with it.
To make Eevee evolve into a Flareon, you have to expose it to a Fire Stone.
In order to evolve Eevee into a Jolteon you need to have the thunderstone in your bag, select "use" and then select your Eevee from your Party. You can't evolve it by making it hold onto the Thunder stone.
no you cant vaperon is one of the many Pokemon that you can evolve FROM an eevee
umm yes it can. if its in the johto league. Answer: you are able to evolve eevee into a espian by leveling eevee up in nightime
Eevee will not evolve because there has not been a new Pokemon invented in which eevee can evolve into.
Shiney eevee would evolve into a shiney flareon.
