No more than 13 maximum on a 20 amp circuit.
You can safely put 48 regular (incandescent) 40 watt lights on a 20 amp circuit. If at some future date you might place higher wattage lights in the circuit, you will want to limit the number of lights to 20.
The voltage needs to be known to give an answer to this question.
A 15a circuit can supply approximately 1650 watts, so 1650/65=25. I would stop at 20.
50 watt equals less than 1/2 amp current flow at 120 volts so you can have 30 light on a 15amp breaker or 40 on a twenty amp breaker.

Provided you use wire that is rated for 20 amps.

Two 20 amp ground fault interrupter circuit breakers are used to power the lights and receptacles for the medium shelter.

If there is nothing else on the circuit then you could easily install 15. If there are outlets on the same circuit then try and keep the total of outlets and lights to a maximum of 15. But in reality the number of devices depends on how many amps each device pulls. Add up the amperage of the recessed lights you are going to install and then add any outlets and what may be plugged into them to get the number you can install. A 100 watt light bulb will draw about 1 amp. So you can easily have 15 on a 20 amp circuit.
The formula you are looking for is Watts = Amps x Volts.

You can plug in as many as you want but none of them will work. An "open" circuit is an electrical circuit which is not a complete circuit and therefore electricity will not flow through it. If you mean an unused circuit,which has no load on it, then the answer is 2 ea. 5 amp devices on a 15 amp circuit and 3 ea. 5 amp devices on a 20 amp circuit. The reason for this is that any circuit is not to be "loaded" more than 80% of the OCPD (circuit breaker amperage rating.
A 20-amp circuit can typically support up to 10 receptacles.
A 30 amp circuit can safely support up to 4 outlets.
