Answer 1

For this issue here is the answer from Google Play Team:

Hi x,

Thank you for your note. If you've lost your keystore you'll have to publish the app with a new package name and a new key. You should also update the description of the original app and unpublish it. Please note that users are allowed unlimited reinstalls of each application distributed via Google Play, an application will remain available to users that have already installed it even after it has been unpublished. Currently we do not support the deletion of apps or the re-use of package names. Unfortunately, there is nothing else we can do to assist you further with this matter.

Regards,

The Google Play Team

As blackbelt stated, if you signed it with a different keystore, it will be a new application. So you should tell your users that they have to download the new version of the app.

However you could check this tool which will try to recover your private key with the alias. I don't guarantee that you could retrieve it but you could give a try.

The tool recovers the key for your alias. By default this is the same like the keystore password. Now there is an option to save the key in a new keystore with the same password than the key! You can use this, to sign your apk and update your app in the Playstore.
