Hand gliders do not exist - just bad grammar for hang glider.
They are Jets, Propelled airplanes and Gliders. Ultralights can also be qualified as a fourth type of airplane.
NASA made the first hang gliders back in the 70's as part of their mars experiments.

Hang gliders and paraplanes are good examples of this.
A hang glider is a fabric wing on a light frame and a paraplane is a parachute with a small motorized cart attached.
