First understand, a circuit breaker doesn't trip on low (60) voltage. It trips on overcurrent, or too many amps being drawn by the circuit.
A 60 volt reading in a 120 volt circuit is a typical "backfeeding" reading. You have something miswired. You may have tied into another circuit on the same phase. Go back and disconnect the feed to your 2 additional outlets. Check voltage on the last outlet on the original circuit. If you've got 120 volt, turn the circuit off, then wire in the first new outlet. Do not tie into any other wires other than the wire you ran from the last outlet in the original circuit. Turn the circuit back on and check voltage. You should have 110-120 volt. Then add the second additional outlet as per the above. Do not tie the neutral into any other wire than the one from the original circuit. This should clear your low voltage problem.
You can provided the protecting breaker for the circuit is 20 Amps or less.
A GFCI receptacle can pass it's "protection" to other outlets wired from it. If the GFCI trips, all outlets wired from it will "trip" also. A GFCI tripping will not necessarily trip the circuit breaker in the service panel.
Yes, if the circuit breaker and the wiring is large enough to carry the sum of the amp draw of all. Without knowing what will be plugged into the outlets, there is no way to be more specific. <<>> It is recommended to use a dedicated circuit for a garbage disposal. It is best not to add any additional loads to kitchen counter receptacles as these are also dedicated circuits.
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.
120 amps The above answer is wrong. A 60 amp breaker is designed to trip at 60 amps be it a single pole, double pole or a triple pole that is used on three phase equipment. The number on the handle of a breaker is the trip capacity.

Two 20 Amp circuits with the outlets staggered so a different circuit is on two adjacent outlets. Should be GFCI protected.

There are tow places to put a Ground Fault Circuit Interrupter. There is a GFCI breaker which would be installed in a breaker box and a GFCI outlet that can be installed anywhere. Most GFCI outlets allow you to connect regular outlets to the GFCI and those outlets will also be protected.

The only determining factor is the size of the circuit breaker that you will be using. If the garage circuit will be protected with a 15 Amp breaker, you may use a 14 AWG wire. If the circuit will be protected with a 20 amp breaker, you must use a 12 AWG wire. Note too that garage outlets should be protected with a GFCI breaker or outlet. If you have any concerns regarding your ability to adequately design and install the garage outlets, please, for your own safety, contact a local electrician.
Go to your distribution panel and shut off the breaker that you think is the circuit in question. If the circuit becomes de-energized then the breaker you just turned off feeds that circuit. Look on the handle of the breaker and the number you see is the amperage of that circuit. <<>> Determination of a 15 or 20 Ampere circuit is normally indicated by a combination of a 20A breaker and a 20A dedicated outlet. A 15A circuit normally has multiple outlets; not typical in a 20A circuit.
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.
Your home electrical wall outlets current capacity is governed by the breaker that feeds that circuit. In most home situations the wall receptacles are fed with a 15 amp breaker. Dedicated outlets could have a higher ampacity as they are installed for specific appliances or devices. To check your circuit, plug a lamp into the outlet. Start flipping the breakers off. When the lamp goes out that is the breaker for that circuit. Look on the handle of the breaker and it will tell you the capacity of that particular circuit.
Don't know what you mean by back wire, but most GFCI outlets have a circuit to attach additional outlets that will be protected by the GFCI. Keep total load in minds.
