I can't down load my updates apps because an old apple id pops up?
Same thing happened to mine. You have to delete all the apps that need to be updated. Then redownload them with your new apple id and password.
You might want to check in Settings > iTunes & App Stores. At the top of that window will be the Apple ID: you are using. If it's not correct you can tap that field, sign out and then sign in with the correct Apple ID.
