The humuculi are created humans modeled after the Seven Deadly Sins - Lust, Gluttony, Sloth, Greed, Envy, Wrath, Pride.
In the original manga and new anime series they are the children of Father.
No, he doesn´t become a homunculi.
No he gets taken into the Gate of Truth by Truth (the white guy).
No, Envy the homunculus was not an alchemist. Homunculi can not use alchemy. Wrath (in the first series) could use alchemy because he had one of Edward Elric's arms.
He was defeated but Ed did not kill him. He, like Wrath were homunculi who could age.
Truthfully, the answer depends on the series. In Fullmetal Alchemist (the anime), Envy is a male. Envy was born from the failed human transmutation performed by Hohenheim after his son died. Like the other Homunculi in the series, their gender prior to the transmutation carries over. As for Fullmetal Alchemist (manga) and Fullmetal Alchemist: Brotherhood, Envy has no gender. The Homunculi in these series are born from the sins of Father, which do not have gender.
There is a civil war between the current homunculi Fuhrer and the forces of Edward Elric who is trying to destroy Father and the homunculi.
Fullmetal Alchemist was created in 2003.
