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.

As a general guideline, you can typically install about 10-12 LED recessed lights on a 20 Amp circuit breaker. However, the exact number may vary depending on the wattage of the lights and any other devices connected to the circuit. It's recommended to consult with a licensed electrician to ensure proper installation and avoid overloading the circuit.
You can safely connect up to 10 70-watt lights on a 15 amp circuit. Each 70-watt light draws 0.58 amps, so you would not exceed the circuit's 15 amp capacity with 10 lights.

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.
You need to address this from the prospective of current draw per light. The length is not really the issue. Your continuous current should not exceed 80% of 20 amps, or 16 amps. Now if you were using certain halogen bulbs the current for each might be 1/2 amp each so you could have 32 such bulbs. Do a sample layout in what is called a reflected ceiling plan (Imagine the ceiling plan on the floor) and see how many lights of what current you plan to use and break up your circuit as needed.
Up to 12 on a 20 amp circuit. Up to 9 on a 15 amp circuit. But use common sense. If the circuit will be heavily loaded, as in a home office, then do not install that many.
