Have 4 iPads that are all logged into the same Apple ID and the person who created the Apple ID doesn’t remember the password and the email is no longer active. Anyways to get the Apple ID off the iPads so I can log into a new one?

Have the person  enter the Apple (iCloud) ID, and click Forgot Password. See if they can get a Rescue or Notification email option. Link to contact Apple Support at the end of the 2nd article.

If necessary, if you are the original owner, contact Apple. Apple can remove the ID  if provided the required paperwork to include the original purchase receipt with the serial number on it.

You used to be able to take the device, the original purchase receipt with the serial number, and a photo ID to the nearest Apple Store (if it has reopened) and have them remove the ID. This may have changed, so call the store before going to make sure they can help.
