You can read the elevation like you are getting lat and lon:
edge.fetchWayGeometry(n).getEle(i)

No, elevation is not read from the pbf. See OSMReader and the
ElevationProvider implementations how this is done.

No. We only read and store data that we need. Sideways are included but
not the building data.
