I want to create an app to register a new fingerprint and add more fingerprint and authenticate in same app, but i am able to authenticate only one with the hardware supported fingerprint only.

So my requirement is:

Register fingerprint as an image scanner through app and send them to db or server. Authenticate scanned fingerprint in same app through db or server where fingerprint was saved.

you can't get fingerprint through device's fingerprint scanner, it just provide authentication result if its success or not, for getting the fingerprint you would need a separate fingerprint scanner and attach it to the device. The in-built scanner doesn't support your use case.
