Nope.  Every account in /etc/passwd needs a real account in Windows,
given as SID in the pw_gecos field.  Cygwin has no own user management
but relies on Windows' user management.

What you can do is to create (or choose an existing) single account in
Windows, create three entries for this user in /etc/passwd, edit
/etc/passwd to give these three accounts different names and different
Cygwin uids, but let them all still refer to this single Windows
account.  And then expect weirdnesses.  For instance, the files created
by any of these accounts will of course be owned by the underlying
Windows account.  An `ls -l' will always show the files being owned by
the user entry showing up first in /etc/passwd.  They are simply only
one account actually, whatever you fake in /etc/passwd.
