Where these apps bought with a old or different apple id? Or have you been using the same apple id?
You can go to settings - app/itunes store - view ID - log out and log back in, if you've been using the same ID.
If you had an old ID, then you will need that ID and password, as all apps are tied to the apple id that was used to purchase it.
