I work on the Lightroom iOS team, and not in Adobe Support, but I can see some limited details that may help. You seem to have tried signing into Lightroom with multiple email addresses, and this has created multiple Lightroom accounts.
The subscribed account for you is based on Apple's social sign-in method, and uses email relay (so I can't confirm the actual email address used). On iOS devices, signing into your paid account simply requires you to choose the Apple sign in method on Lightroom's login screen (assuming you remain signed into the same iTunes ID in device settings).
However, if you wish to sign in on Android, I'm not sure how that works -- you probably need to provide the email address you use for your iTunes ID.
If you need more help, please do not post your account email addresses here. Instead, please contact Adobe Support at https://helpx.adobe.com/contact.html?rghtup=autoOpen ...and in the chat field (lower right), type AGENT to get to someone quickly
