This is what is known as three way switching in the trade. See related link below for wiring diagram. believe it's like this
(this circuit would work but it may be done differently by licensed electricians - I'm an engineering student, not an electrician

a single pole double throw switch at each end of the light terminals, either the light is connected to two different rails and will shine, or connected to two rails of the same potential and wont shine
Using 14/2 or 12/2 wire, black, white and bare. Bring the hot/black wire in the light down to the switch on the black wire, through the switch and back to the light on the white wire. Connect the white wire in the power wire to the white wire in the light. Connect the white power wire from the switch to the black wire in the light. Run the black and white wires in the first light to the second light. You should wrap the white power wire from the switch with black electrical tape to cover the white so that the next person realizes it is a power wire.
At the lights there is a black, white and bare wire from the supply. With power off you would break the black (Hot) connection at wirenut. Then you just need to run a wire to and from the switch. Assume you use standard Romex with black, white and bare wires. Connect the black wire to the black wire from supply. Connect the white wire going to the switch to the black wire going to lights. Wrap black electric tape around each end of white wire to show it is HOT. At the switch end connect the white wire to one lug on switch and black to the other. Connect the bare wire to ground on switch and at light to other bare wires.
The terminology for this type of installation in North America is called three way switching. Here is a simple diagram showing power to one switch, a 14/3 wire running to the second switch, and the light(s) being fed from the second switch.

For the simplest installation, ALWAYS run the 3-wire cable directly between the switches. Keep it out of the light fixture!
There are many, many, many variations possible, but this is simple, easy and nearly foolproof. Good luck, and hope this helps some.
Before you start this process make sure to take several saftey precausions. While wearing latex gloves pinch the first black wire while twisting the red wire around it. A separate set of wires can be purchased at your local Home Depot or Lowe's. These wires should be ran through the top of the wall. At the other end of the wall you should have your light switch when it is turned on the light should come on if this does not work replace your light bulb and try again.
This is done using two two-way switches, switches with two switching position. The input live wire from the circuit breaker goes to the middle point of one switch. The output live wire to the light is connected to the middle point of the second switch. The two remaining points from one switch are then connected to the two remaining points on the other switch. The neutral from the light goes straight to the neutral bar in the Distribution Board.
Does power come into to lights or switch first?
Use two three way switches. Hot feed comes to one switch. Wire to light goes from other switch. Two travelers (same size wire as other wires) are needed between the two switches.
parallel. research. but the clue is wire up both neutrals. then put the pluses in series parallel. hard to draw you a schematic on wiki.
yes like a hall light.
You need two separate switches. You can get two switches that are in the same form factor as a single switch (2 gang switch). You use one switch for the outlet and the other for the light. You switch the black wires which are "hot".

Three wire strand running between 2 switches is for a 3 way switch. It is only one side of the circuit. Since it is only one side and switches between the 3 wires there is no way to use it for a light. There may be power at the hall light, but I have seen all types of wiring and each circumstance has to be looked at on it's own.
It provides switching for a single wire. It has one input and one output. When the switch is open (Off) the input is not connected to the output. When it is closed (On) the input is connected to the output.

Tie all White wires together. Tie the Grounds together and connect them to the ground screw on two switches. Create a pigtail with TWO black wires coming out. Connect a black wire to each of the two switches. (you pick which screw, but be consistent. Connect the black wire from the light to the remaining screw on one of the switches. Connect the black wire from the fan to the remaining screw on the OTHER switch.

You will need two 3/way switches and two 4/way (Intermediate) switches. Click the link to see a video of exactly how to wire such a circuit.
On these types of installations an electrician would use a three wire cable set from the switch box to the fixture's junction box. At the fixture's junction box both the fan neutral and the light neutral would be wire nutted together with the incoming neutral from the switch boxes. From the three wire, the white wire would go to the fan and light's neutral wires. The Black would come from the bottom of one of the switches and go to the fan's motor lead. The red wire would come from the bottom of the other switch and go to the light fixture's lead. It can be done with two runs of two wire to the fixture. You will need a two gang switch box for this project to hold the two separate switches. You could use a single gang light switch box if you can still find where duplex switches being sold. A duplex switch is one that has the configuration of a duplex receptacle with the switches being one on top of the other. The cover plate is the same one used for duplex receptacles. To answer this question fully more information is needed. See discuss in the left margin.

Connect the incoming power to the line side of the GFCi outlet. Now run another wire connected to the line side of the GFCI outlet from the GFCI outlet to the switches. Power one of the switches and use that switch to turn on the 2 lights. Run power from that switch to another switch and use that switch to send power to the fan. Mount both switches in a double pole switch box. If the light above the sink has an outlet on it then you will have to connect power going to that light on the load side of the GFCI outlet. If not then just connect it to the line side.
It provides switching for a single wire. It has one input and one output. When the switch is open (Off) the input is not connected to the output. When it is closed (On) the input is connected to the output.
A two way switch is required for staircase wiring. A staircase switch will have two terminals. Connect the line wire with the center terminal. Connect the two ends of a wire with the top two terminals and two ends of a wire with the bottom two terminals. The line wire at the center terminal can now be connected with one terminal of the light bulb or light holder.
You cannot wire a single pole switch and 3 way switch together.
You don't. You use a pair of two-way switches ('three-way switches' in US/Canada).
