How can delete an app from iCloud?

What exactly are you trying to do? You can never delete an app from iCloud. All of your past purchases are forever linked to your Apple ID and all purchases are available in iCloud as long as the content is still available from the iStore in which it was purchased.

If you want to remove an app from/no longer use an app with iCloud Drive turn it off in the iCloud Drive Settings.
