Is is not clear what the question is. As far as #4 is concerned, a catenary cable will have tension, and if the span is greater than zero, there will be a horizontal component to the tension. Also if a load (the light fixture) in addition to the weight of the cable is added, it will not actually be a mathematical catenary, though this may be a technicality.
