Maximum flight altitude: The maximum allowed flight altitude is 120 meters (= 400 feet) in Nepal.
Maximum horizontal distance and FPV: All flight operations must be in sight. A horizontal distance of 500 meters (= 1650 feet) is given as a guideline.
Compulsory insurance: Even if it is not stipulated, you should take out a personal liability insurance for drones.
Maximum take-off weight (MTOW): Up to a weight of 2 kilograms, drones are allowed to fly on private land without permission. With a take-off weight of more than 7 kilograms, the maximum flight altitude is 200 feet (60 meters). Drones may weigh up to 20 kilograms.
Distance to airports: Unfortunately, I have not found a specific guideline, but you should keep several kilometers distance from airports.
Other safe distances: As I understand, drones with a camera are classified as Small Unmanned Surveillance Aircraft, for which certain minimum distances (150 meters to crowds, 50 meters to buildings and vehicles) must be observed.
Flight bans: I do not know any special flight bans for drones in Nepal.
Flight approval: In Nepal, the flying of a drone is permitted in principle, but you must apply for an authorization from the Civil Aviation Authority Nepal (CAAN) if you want to make film recordings.
Time of operations: In Nepal, drones may be operated only during the day.
Specific regulations: Because of the high location, the air is partly very rare. Not all drones can fly at these heights. Before your Nepal trip, I would check if your drone can fly in these regions.
Regulations for commercial pilots: Commercial copter users need permission from the authorities.
Good to know: I would be very sensitive at Hindu temples, because Hindus often do not like that other believers see certain parts of their temples. Ask beforehand!
