You can't 'make' one, they appear when a Creeper is struck by lightning. However in the latest updates, work is being done to let (on server-side) monster spawners spawn variant creatures like Spider Jockeys and Charged Creepers.
Yes.But I not sure because I see the minecraft wiki of creeper.
2 hits with a diamond sword but keep moving and jumping. It's also a good idea to be far from a creeper as possible. A creeper can explode anywhere and any time. Make sure that you wear armor before you go "hunting". But I doubt that would do you any good.
