Windows 10: How is the email attached to Microsoft 365 NOT a Microsoft email???

I purchased a laptop for my business before purchasing the Microsoft 365 package with my business account. I quickly set up the administrator using an old Hotmail account. Now I can't change the administrator because apparently my business account, attached to Microsoft 365 where I receive email through outlook, is not a Microsoft account. Please help!!!

Office 365 Outlook email accounts

The reason I am asking these questions are that two individuals are buying two new laptops and would like to share one Microsoft Office 365 Personal.
A has a subscription to Microsoft Office 365 Personal already and wants to share the same account with B.
I have installed Microsoft Office 365 Personal in a second pc B and when launching Outlook all my email accounts from A were loaded. So, I cannot figure out how to install Microsoft Office 365 Personal in a second pc so that my email accounts A are not loaded.
This raises more questions for me.

1. So this
   • User A installs and activates O365 on User B's laptop
   • User B adds his / her email accounts to Outlook
   would not apply to Microsoft Office 365 Personal as it breaches the licence agreement?
2. Am I correct?
3. If it does apply how can I install Microsoft Office 365 Personal in a second pc so that my email accounts A are not loaded, and I can only add B email account on the second pc?
4. Would B be able to access A OneDrive?
5. Or would B have a separate 1TB free space in One drive, or only the free 5GB or none at all?
6. And most importantly is this even legal or in breach of contract as Microsoft Office 365 Personal is for one user only?
