i recently did a hard reset on Tecno N2S android 5 device. the problem is it has FRP factory reset protection and i don't know the email that was previously used . is it possible to know that email?

It most likely would be a Gmail. If not, no there is no way to find out unless you start checking all your accounts.

Are you the original owner of the phone?

No...and still the owners email didn't work

Do you know the original owner? If you do a factory reset without first properly removing the Google account, the phone will prompt you for that Google account and password. If that's the case, then contact the previous owner and ask him or her to help you log back in using their Google account.
