I was wondering whether Prahaar is a supersonic or Hypersonic missile.

Prahaar gross data parameter is not repoted in mainstream media. Only tarmak007 blog reports the following:
Like other Indian missile test reports these numbers indicate it was a non-ballistic flight (depressed ballistic trajectory does not result in that kind of flight time, range and altitude.
The missile sees its MaxQ during ascend (given its AAD / ABM pedgree) at 2 MW drag dissipation. The top speed is 4.5 to 5 Mach.
Clearly there is no need for payload separation thus its does not have a RV, in essence very similar to Shourya in many aspects of flight and maneuver. rolling to spread the heat, and thus in that configuration gliding is a freebee. This craft is capable of glide. and given the claimed precision it will be used in glide mode, with considerably longer range than the claimed 150Km ballistic range. Even the claimed 150 km range with 35 Km apogee is sub optimal.
Lot of data and technology learned from Prithvi and Shourya was applied to used this AAD vehicle as SSM.
------------ Added later ------------
During ballistic decend the velocity is between Mach 2.5 to 3, so the tail fins work well. At such slow speed if flying ballistic trajectory the craft can be taken down by SAM. All the more reason not to fly ballistic trajectory.

PRAHAAR
The missile with a length of 7.3 meters and diameter of 420 mm weighing 1280 kgs, and a single stage solid propulsion system goes to a height of 35 kms before reaching the targets of the range of 150 kms in about 250 seconds.
