Answer for USA and Canada power supply service. Presuming a "15 amp circuit" is meant as a 120 volt system with a 15 amp single pole breaker with #14 awg wire, then: Per the National Electric Code, a breaker can only be loaded to 80% of rating. Thus, a 15 amp breaker can only feed a 12 amp max load. If the loads that will be plugged into the receptacles are unknown, then 180 watts shall be used for each duplex receptacle. Maximum load allowed on the breaker is 120 x 12 = 1440 watts. Maximum receptacles allowed on circuit is 1440 / 180 = 8. Still, read the NEC or other required codes depending on the installation location and connected equipment. In Canada, there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.
The National Electrical Code allows a maximum of 10 receptacles on a 20 amp circuit. However, it's recommended to consult local building codes as regulations may vary. Additionally, the number of receptacles on a circuit should not exceed the circuit's load capacity to prevent overheating and potential hazards.

It depends on the capacity of the circuit. A typical residential circuit in the US is rated for 15 or 20 amps.
Eight on a 15 amp circuit, tweleve on a 20 amp circuit, including the gfci receptacle itself.
Provided you use wire that is rated for 20 amps.
Yes, you can use an 18 amp appliance on a 20 amp circuit. As long as the circuit has a higher amp rating than the appliance, it is safe to use. Just ensure that the appliance's amp rating does not exceed the circuit's capacity to prevent overloading and potential hazards.
A 32 amp fixture can not be fed from a 20 amp breaker as the breaker will trip every time.
No more than 13 maximum on a 20 amp circuit.

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.

A 20 amp circuit be used for any device that takes up to 20 amps to make it operate.

15 amp outlet on a 20 amp circuit.
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.
Usually a 15 or 20 amp breaker is sufficient
