My company wants to use Office 365 user credentials to logon on computers. I went as far as creating an on-premise Domain Controller and installed Azure AD Connect. But Office 365 users are not being created in the Domain.

You can try forcing a full password sync using powershell.. Open the DirSync PS console (C:\Program Files\Windows Azure Active Directory Sync\DirSyncConfigShell.psc1)
and run:
Set-FullPasswordSync
then
Start-OnlineCoexistenceSync
I suggest you read this MS article:
Specifically this section:
Single forest, multiple sync servers to one Azure AD tenant
Having multiple Azure AD Connect sync servers connected to the same Azure AD tenant is not supported, except for a staging server. It's unsupported even if these servers are configured to synchronize with a mutually exclusive set of objects. You might have considered this topology if you can't reach all domains in the forest from a single server, or if you want to distribute load across several servers.
You CAN have one or more STAGING servers, but they are only for DR purposes and really aren't even needed short of remembering your configuration/sync settings.
If you export and document your AADConnect settings/mappings/customization then you can just as easily rebuild a new AADConnect server in a DR scenario.
You CANNOT have more than one AADConnect sync server in your environment connecting to the same Azure AD tenant.

If you want to login on workstation using Office 365 account, you need a Windows 10 Operating System

If you already have an Active Directory on Premise, you can synchronize AD Account into Azure AD. You can also use only Full Cloud AAD users to login (with Windows 10)
