Arbok does not evolve in Pokémon Crystal.
Arbok is a fully-evolved Pokemon, thus it cannot evolve into any other Pokemon at all. Hope that this helps.

I think you would get an F if you were quizzed on Pokémon. Why do you think it evolves into Seviper? Arbok does not evolve, and Seviper is just a whole different Pokémon. It's ok if you were confused because Jessie used to have an Arbok and she gave it up and got Seviper, and you thought that her Arbok had just evolved. Hope I helped! :)
ekans evolves into arbok at level 22
No, Sneasel cannot evolve in Crystal.
You cannot evolve Misdreavus in Crystal.
I would say that the best way would be to get an ekans then evolve it
