Safe boot refers to when the system is starting up - safe mode is when the system is actually running - and safe login is when the system starts up the user session.
Launch daemons and startup items are launched during system initialization by the system launchd process on behalf of root. Launch agents and login items are opened during the initialization of the GUI environment by the user's launchd process.
