They stay until you delete the headstone or urn, which is the source of the haunting. After which life returns to normal.
You can't. The ghost is programmed to go away at around 4:00am and come back the next night. This cannot be changed and as far as i am aware there are no cheats for this. Sorry
It only takes about half a second for a ghost 2 disappear.
No, that comes in the Sims 3, but there is a ghost hack found in sim2wiki
No, in the sims 2 Free time your sims can not get married to a ghost.

your sims has to be a vampire and die of thirst. or you can get an orange ghost by dying in a fire.
the ghost is in the living room and it can move or disappear
You can't play as a ghost, they are not controllable.
There is no such thing as the ghost world.
no you cant become a ghost in the sims 1. If you die there only comes a thombstone that's all.
