go to your house, invite them over, talk and ask them to move in! (hope they say yes)
No unfortunately you can't but you can make them move in with you by going onto actions

You have to invite him or her to your house and find the ask to move in option when you click on them

You can't

You don't, stupid
If you mean put new wallpaper in your house, go to move/sell items and click on the wall. If you mean buy new wallpaper, I'm supposing it's in the sims store.
You can get married on the Sims 3 ambitions
yes if you do not already have the maximum amount of sims in that household
Your sims baby will be ALLOWED to move out when it is a young adult, but can have their own home as a teen if an adult goes with them and the adult dies or is killed.
