Answer 1

Yes.

is there a way to reactivate the app even after hard reset

The user would have to reinstall it and set it up again as a device administrator.

If the app is removed, is there an option to trace phone location using IMEI number.

Not in standard Android.

How to the prevent the app from deleted when doing a factory reset.

Build your own device that has your app pre-loaded onto firmware and set up as a device administrator.
