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.
A "dedicated" circuit is one to which only one device is or can be connected; therefore the circuit is "dedicated" to the device. A NON dedicated circuit will therefore be one to which multiple devices can connect, such as the wall outlets in your home. Multiple wall outlets are connected to a common circuit breaker, making that an example of a non-dedicated circuit.
Any appliances that draw over 1500 watts should be on a 20 amp circuit.
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 check if the required input voltage of the refrigerator is actually 110 to 120 volts and preferable use an exclusive circuit having a 15 amp breaker for residential of commercial use. In most cases, this is fine. However, if, on the off-chance, your refrigerator's installation manual or rating plate tells you that it needs its own 20 amp circuit, then a 20 amp receptacle must be used. Note: An outlet on a dedicated circuit MUST NOT be rated less than the over-protection device (fuse or circuit breaker) protecting that dedicated circuit. By the same token if you are using a 20 dedicated circuit then the wire rating has to match the amperage. #14 wire is rated at 15 amps, # 12 wire is rated at 20 amps. SAFETY ADVICEBefore you do any work yourself,on household electricity supplies, equipment or appliances,always turn off the powerat the breaker box/fuse panel BEFORE you attempt to do any work ANDalways use an electrician's test meter having metal-tipped probes(not a simple proximity voltage indicator)to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.ALWAYS CHECK WITH YOUR LOCAL WIRING SAFETY OFFICE BEFORE YOU ATTEMPT TO CHANGE ANYTHING- BREAKER PANEL, BREAKERS, CABLES OR OUTLETS -ON ANY ELECTRICAL CIRCUITS.
A 2C #14 will be suffice but it should be the only device on the circuit. This is known as a dedicated circuit.
No. Each circuit has to have its own dedicated circuit. The breaker and wire size differ between the two appliances.

Dishwashers do not have to be on a dedicated circuit, according to NEC codes. Neither do refrigerators. Electric Ranges and OTR Microwave Hoods and Hood Fans do. First, always ascertain the appliances that will be in the room and regularly used, and calculate their wattage or look it up in the specs found on the appliance or in its manual. The dishwasher issue is a falsehood espoused by many kitchen designers, home inspectors and electricians who have apparently substituted their own opinions as being code. I just read all of the applicable NEC codes. They are readily available for purchase or for free at your local library. Consulting it yourself is the best bet. It does not specify a dedicated circuit for the dishwasher. It can be on a branch circuit for the kitchen, but if it's sharing the circuit with other appliances, then it must not use more than 50% of a branch circuit's load capacity. So that in effect creates a dedicated circuit requirement IF your circuit is a 15 amp circuit. If it's a 20 amp, you may have capacity room for a small load appliance such as the disposal or refrigerator, depending on load calculations (Volts x Amps = Watts (Load). But if you use a 30 amp or higher circuit capacity, then you can comply with code much easier if other small appliances are on it. NEC 210.23
A 15 amp dedicated circuit breaker should be used for the dishwasher. The disposal can be wired to the general kitchen 15 amp circuit.
Yes, but check if the required input voltage of the refrigerator is actually 110 to 120 volts and preferable use an exclusive circuit having a 15 amp breaker for residential of commercial use.

A dedicated circuit.
The wire in a circuit helps to pass power to the electrical appliances.
