I have accidentally deleted my keystore file and now I can't update my apps in Google Play, I only have the SHA1 Fingerprint from it, and I want to know if there is a way to create a new keystore and insert that SHA1 code there, so I can use the keystore to manage my apps again... Is there any way at all to do that?

The answer is NO.
If you have lost your keystore file then you can't update your application further more. You need to generate a new keystore file. For that you need to also upload your application with different package name with newly generated keystore certificate.

You might want to try to restore a deleted keystore file using various data recovery tools. Generally, the only advise that exists on keystores: always backup it.
