Of course, there are types for almost all of these versions. Like Windows 7 has Home, Business, Ultimate, etc. Vista had Home, Professional, Ultimate, etc.
These are just desktop versions of Windows too. There were also "workstation" versions of Windows prior to Windows XP.

Windows 2000 Professional coincided with the Windows 98.
And all of this doesn't take into consideration "server" versions of Windows like Windows NT Server, Windows 2000 Server, Windows Server 2003 and Server 2008, etc.
