if you provision 100 users via cloud and their UPN is in format USER@CONTOSO.ONMICROSOFT.COM, will the generated TEMPORARY password not be affected if we change the UPN OF 100 USERS to CONTOSO.COM?

No, it will not. Remember to let them know about the new UPN value though, otherwise they will not be able to login.
