I believe there are no Pocket Monsters going by the name of Ho-ho.
If you are referring to the legendary Fire/Flying Ho-oh, it's right at the lava/volcano maps. It's pretty rare, so keep hunting!
You can't catch Ho-oh in Pokemon Pearl or in Pokemon Diamond, but you can migrate Ho-oh in pal park from a GBA game.
After getting the rainbow wing from the radio director in Goldenrod city, go to the top of Tin tower in Ecruteak City and battle it.
You have to purify every shadow Pokemon
No, because it is a legendary Pokemon.
