It depends on the wattage of each bulb. Typically you only want to load your circuit to 80% of its rated capacity. Hence a 15 A circuit would be .8 x 15 Amps. Now if you had all 60 Watt bulbs and the supply voltage as 120 V then you could support 24 such bulbs. The key formulas are Voltage = Current x Resistance and Watts = Voltage x Current in your lighting example. However, if the lighting fixtures are rated for a higher value and you just choose to use 60 watts, you should size to the rated capacity of the fixtures on the circuit since someone else may later put in the maximum rated bulb.
A 15 amp breaker protecting # 14 wire.
Depends on the wattage. For example a 60W incandescent bulb draws about 1/2 amp so you could have thirty. Since you typically de-rate to 80% of the value of the breaker it would be 24.
50 amp breaker.
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
I have never heard of a 13 amp plug. However, each flood light would draw about 4 amps since you calculate amps by watts / volts. You just add amps to determine total load.
No more than 13 maximum on a 20 amp circuit.
#12/2wground & a 20 amp breaker should be enough for lights,receptales.
Should be fine if that is all that is on the breaker.
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.
The voltage needs to be known to give an answer to this question.

A 32 amp fixture can not be fed from a 20 amp breaker as the breaker will trip every time.
Replace the 30 Amp Breaker with a 15 Amp breaker.
A 50 amp breaker is an overcurent device.
