I would suggest using CyberTracker <https://www.cybertracker.org/> for this
job. There might be other applications doing the same thing, but the nice
thing about CyberTracker is that you can set it up to record exactly the
information you want to record (e.g. computer name or IP address or take
picture) and afterwards import the data from all the different GPS devices
to a single file/database which can be exported to a .shp file (basic
vector file format used by QGIS).

QGIS can do all of this. You can either have that information (country,
state, suburb and postal code) in CyberTracker and record it when you take
the GPS point, or afterwards add it to the attribute file (.dbf) of your
shape file (it can also be stored in a PostgreSQL (PostGIS) database from
QGIS, although I have never used this and don't know how easy it is to set
up).

Yes, by editing and adding new columns to the attribute table of your shape
file; easily done.

You can select on any column the values you want and zoom to selected
values in QGIS.

Yes

It can.
