No. In a 20 amp circuit all wire has to be 12 AWG or larger.
Yes, you install a GFCI on a 2 wire circuit.
In the United States and according to the NEC, in commercial and industrial installations, you are limited to 10 receptacles on a 15 amp circuit. The size of the wire is not a determining factor. There is no limit to the number of receptacles on a circuit in a home and there may be local codes where you live that have stricter requirements.
A #14 copper wire rated at 15 amps is the minimum size wire for a 15 amp receptacle.
No, not in the North American electrical system. Opening up a neutral on a three wire circuit could create a series circuit if two devices are plugged into the same receptacle. This is how kitchen counter receptacles are wired in all new homes.
Wire size is governed by amperage not voltage. Voltage is an insulation factor when talking about wire. Add up the amperage of fixtures you want in the circuit. Once that is found then the size of the wire can be calculated.
Each of the circuit breakers in the service panel controls electricity on a branch circuit. A branch circuit is typically a loop of wire that runs from the service panel, out to receptacles, light fixtures, appliances, etc. and back again.

The last fixture in a parallel circuit is wired the same as the first. In North America, all of the fixtures are wired black wire to black wire and white wire to white wire. The black wire being the "hot" wire and the white wire being the neutral wire.
The receptacles will be wired in parallel with each other.
Yes as long as you stay within your local code. Usually a combination of lights and receptacles cannot exceed ten total. Do not wire any light to a circuit that requires a dedicated circuit, such as a refrigerator, dishwasher, etc.
How do you wire 2 receptacles together
There are typically 8 to 10 receptacles on most house circuits with special applications in Kitchens. The wires are in parallel with Black to Black, White to White and Bare Wire Ground to Ground.

It sounds like you have inadvertently picked up a feeder from another circuit in one of the junction boxes that you changed the receptacles in. First of all go back and try shutting on the breaker above the breaker that you turned off when you did the original receptacle change. If the 220 volts disappears then this is the circuit that you have mixed up. If the voltage did not disappear then shut the breaker off below the breaker that you turned off when you did the original receptacle change. If the 220 volts disappeared then this is the circuit that you have mixed up. In home wiring many times a three wire will be taken to the first receptacle box from the distribution panel. The red and black wires will have 220 volts between them and 120 volts from these two wires to white (neutral) wire. Start over by removing all of the receptacles that you installed. Look inside the boxes to find where the three wire starts in the two circuits. Use your voltage tester to find the corresponding breaker for the red wire and the corresponding breaker for the black wire. Depending on what colour the original wire circuit was on the original breaker that you shut off, follow the voltage through the remaining boxes and connect that wire to the new receptacles. Maintain the white wire through out the whole circuit and install it on the silver coloured screw on the receptacle.
