How do unlock an iPad with the Apple ID on it.

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. 

Request additional support for unlocking your device.    -

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.

I have several iPads that have Apple ID and I can't use devises.

You would need to use the apple id and password that was used to set up the ipad to remove the icloud activation lock.
