In theory, as many as you want. However, the circuit supplying the receptacle(s) you are using has a maximum capacity before the circuit protective device opens (usually a fuse or circuit breaker). Since appliances come in many sizes / wattages, there is no single answer. Some large appliances require a dedicated circuit with only one single receptacle, so that other things can not be plugged in at the same time on that circuit. Conversely, a 15 amp general purpose circuit could probably handle 100 clocks. first determine how many amps the circuit is fused at. then how many watts the appliances use that are on the same circuit. then you take the watts divided by volts (120) = amps....add them up.

Yes but the circuit must be capable of supplying the sum of the currents needed for the two appliances.
Appliances have to be connected in a parallel circuit to keep the voltages the same for each appliance (they were designed to work with one voltage) , this does not mean that the power output will be the same, the more appliances there are the more current (i.e. power) will be needed to for the appliances and this can go on until the grid cannot supply any more (and you blow a fuse)
Overloaded circuit. Blown fuse in house fusebox probably.

since circuit breaker consists of coils they get heated up when high current flows, when this happens the coil get energised and pull the moving contacts to open thus the circuit breaker opens when high current flows.
Appliances usually have a higher current draw that is very close to the limit of the circuits capacity. By having other loads on this circuit it could lead to nuisance tripping when and if both the appliance and the additional load were started at the same time.
In a well designed house the lights are not connected to the same circuit as an appliance. If by going out you are saying that a breaker trips, then your appliances and lights combined are exceeding the rating of the breaker. You either need to rewire and balance the loads better or plug high current appliances into different outlets on another breaker. If you are not tripping breakers, but lights are just dimming you have a bigger problem with inadequate current supplying your house.
The most likely possibility is the refrigerator has a problem and needs to be fixed. Another possibility is the refrigerator is on a circuit that does not have enough current capacity to operate it and other appliances that are on the same circuit.
The same voltage is present but does not run. It is the current that could be described as "runniing" through the different branches. Just by definition, parallel circuits necessarily have the same voltage. It is architecture of the circuit.
