This is completely dependent on how the game is set up. In certain games, I can only think of Halo III, as long as one player has gold up to four people can play online using the same console. The majority of the games that allow two people to play online using the same Xbox 360 only allow two people to play at a time and both of them must have a gold subscription. If you are looking for a game that allows this I recommend researching specific games before purchasing because they are fairly rare especially in the first person shooter genre.
No, you cannot play cod world at war online with two players on same console and samething goes for call of duty 4. But you can for halo 3.
Many people do, all over the world.
I don't think people can see if you're online when you are using mobile. For instance, if you are using a computer it doesn't show when people pop online; for mobile or computer. Hope that helps
No

Depends on what kind of mods you're using, and for what console you are using them with.
The only way to do this is if you have it for PC using console commands. Even using console commands to change your wife/husband you will mess up the game.
Well it depends on what console your using but the only way to do that is by modding your console
