Levels 1 and s/S define distinct states. The former has file systems
required for multi-user operations mounted; the latter unmounts them. You
would use the "s" (or "S") state is recommended for system software
installation/updates on HP-UX and, if I recall correctly, on SCO.

HP-UX 8.x perhaps; 9.x uses this as "multi-user without X".

For 9.x and later, this is the "multi-user with X" state.

Level 5 is "shut down and power off the system."

Same for HP-UX 10.x and Solaris 2.5.
