I cannot update the apps

Were those applications downloaded with a different appleID to the one you are signed in with now?

if not, try logging in and out of your Apple ID within the apple store.

If yes, you'll have t delete the applications, and download / re-purchase them as the applications are tied to the Apple ID that originally downloaded them.

The message is stating that those applications were purchased and downloaded onto the machine using a different Apple ID other than what you are logging in with, is that the case?
