The "gi" stands for gobject-introspection.

Instrospection is available for any library with a gobject-introspection
typelib. That includes glib and GTK and most of the gnome
stack. /usr/lib[64]/girepository-1.0/ will contain the typelibs
available on your distribution. There will be many of them.

No.

I am not certain what you mean but gobject-introspection provides
bindings for C libraries written to GObject conventions which make them
available to higher level languages such as python (pygobject),
javascript (gjs) and guile scheme (guile-gi and g-golf). pygobject is
widely used; gjs is used by gnome-shell amongst others.

It will mainly work although I believe there are a few missing pieces
which you are unlikely to encounter. Look at some of the examples in
the guile-gi repository. Also look at g-golf.
