Asking how many lights can be connected to a breaker is like asking "How long is a piece of string?".
The total amperage of the lights you want to use together at any one time must not exceed the safe load current of the circuit breaker on your lighting circuit.
It is impossible to give a general answer because the total number of lights that can be installed will depend on the wattage and therefore the amperage drawn by each light and also on whether or not they will all be switched on together at the same times of day or night.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

A light switch is to be used within its ampere rating. You would have to calculate how many amps each light needs then divide that number into the ampere rating of the switch. Round down, do not exceed the whole number.
Example: a 75W light bulb would need 0.625 amps at 120V (I=P/E)
a 15A switch could have 24 75W light bulbs (15/0.625)
The number of switches is not really relevant, it is the total load that matters. It must not exceed 15 Amps
The NEC does not limit the receptacles in a residents. Industrial it is limited to 180 watts each.
No, they each need their own breaker of the right amp. Neither of them would cause the breaker to trip if there was a problem.
Yes, you can. It will be fully protected as it can actually handle a 30 amp breaker.
I've never heard of a 50 amp b-e-a-k-e-r. You can put a 50 amp b-r- e-a-k-e-r in a 60 amp panel; but you can only have an additional 10 amp breaker along with it. You may need to consider adding another larger panel or a separate 50 amp breaker box.
If your question is can you use a #6 flexible SOOW cord and put a 30 amp plug on it, then yes. The breaker that feeds the receptacle that the cord will plug into can be no larger than a 30 amp breaker. What limits the cord capacity to 30 amps is the ratings of the plug on the end of the cord.
A 32 amp fixture can not be fed from a 20 amp breaker as the breaker will trip every time.

If you put a 85 amp breaker in there it will overheat from the starting and stopping of the motor. The extra size of the breaker insures that the furnace will run without interruption and without overheating the breaker. And electric motor can draw three times the amperage rated on start up momentarily. This is why there is need of extra amperage ratings.
Not legally because the rating of the 30 amp receptacle would have a 50 amp breaker ahead of it. If you reduced the feed breaker to 30 amps and still use the #6 wire, this would be within the electrical code rules.

20-amp breakers can be found for many different voltage levels. The higher-voltage ones tend to be more expensive. A breaker can be used in a circuit of equal or lower voltage than the rated voltage of the breaker.
No, the breaker size is too big. A 1 HP, 230 volt motor draws 8 amps. The electrical code recommends for a motor with a full load amps of 8 amp that it use either 25 amp non time delay fuse, 15 amp time delay fuse or a 20 amp two pole breaker. These sizes will work up to 11 amp full load amps.
As many as you need. Just make sure the main breaker of the subpanel stays below 50 amps (the rating of the subpanel) and the input to the subpanel, whichever is lower.
For safety reasons ( and the National Electric Code) never put more than 75% load on a breaker, so for you case, 20 amp breaker x 75% = 15 amps 15 amps x 240 volts = 3600 watts 3600 watts
