EGPWS Glide Slope Warning

If you are manually flying (AP/AT/FD OFF) an ILS approach and below 1000ft you descent below the G/S EGPWS Limit for the "Glide Slope" callout, will it sound? You didn't armed the APP mode! And are flying without Autopilot/Flight director or Auto throttle.

Yes, the GPWS G/S mode operates when a valid ILS signal is being received irrespective of AP/FD/AT use.

Yup, if you have a valid ILS/GLS, IAN "signal" and if IAN is available even in LNAV/VNAV the callout will come, no matter if you fly raw data, manual or automaticly.
