Does this plugin add other metadata like frame depth, height, width, channels etc to the gst buffer ? #20

That information is added to the header stored within the buffer itself. See https://github.com/WKDSMRT/realsense-gstreamer/blob/4c11e3d64ae67fea84db77145743db8522d3989a/src/common.hpp#L38

It is possible to add these info to the gst meta struct ? Any reason why it is not added to gst meta ?

why is get_distance (int x, int y) function not called on the depth frame ?

I see only get_units() is called on the depth frame.

The information you're asking for is already part of the required GstMapInfo. GstMeta is for adding custom metadata that would otherwise not be a part of video/audio.

get_distance is an analysis function. This plugin is a source, only providing the data for downstream use. get_distance should be called in a downstream module where you implement your processing of the depth frame.
