There are multiple ways to wire a switch. If power is fed into the switch box, a second light would be wired one way, if power is fed into the light box, the second light would be wired a different way.
This seems like it would be a task better given to a qualified electrician or local handyman.
If you have good access to the wiring this is relatively easy to do. Each of the 10 lights is connected to another in parallel in a "daisy chain" fashion. Light 1 is connected to the switch, light 2 is connected to light 1, light 3 is connected to light 2 and so forth. Let's say it is light 5 that you wish to switch separately. You can first install the new switch by either adding a new box or modifying old switch box. There are two gang switches that will fit the form factor of a single switch. TURN OFF THE POWER TO SWITCH BOX. Using the same supply input at original switch, add a new black wire to the wire nut for input to original switch and connect this to the input of new switch. Then run a new wire to light 5 and connect black wire to the output of new switch. Connect all the white wires together in switch box and separately connect all bare wires together in switch box. Now at light 5 undo the black and white wire coming from the fixture, and reconnect the wire nuts so that there is a direct connection between light 4 and light 6. Do the same for the ground if present (bare wire). You now have the fixture wires hanging free. Now connect the black wire from new switch to the fixture black wire and white to white and you are done.
Run the power line to a light box in each room, then drop a switch leg from each light box. The power line should daisy-chain to each box, with a "tap" off for the lights of each room. If you do not have experience with lighting or switch logic, it would be much more safe for you to contract with a qualified electrician.
You would need to purchase a duplex switch. As for the pilot light look for a duplex switch that has a neon pilot light that is incorporated into the handle of the switch. When the switch is turned on the switch's handle will illuminate.
The switch sounds like it might be arcing. Switches are inexpensive, change it out with a new one. With the power off and the old switch removed check the connections in the switch junction box for loose splices or burnt wire nut connectors. If everything is fine there check the light junction box for loose connections.
The pre wire for a ceiling fan light should be made with a three wire cable. This cable will have a red, black, and white wire as main conductors. This cable will also have a bare ground wire. This wire should be strung between a two gang switch box to the fixture junction box. This pre wire allows the supply to be either fed to the two gang box. From the two gang switch junction box, one side will be used for the light in the fixture and the other side of the switch junction box, itwill be used for the fan portionin the fixture.
Yes this is done all the time in house wiring. The power source is brought to a light switch's junction box. The source for the light is taken through the switch to turn the light off and on. The same source feeder is then taken to receptacle junction boxes to power devices that have to be plugged in.
Standard is 48" to the top of the switch box.
To replace a double light switch, first turn off the power at the circuit breaker. Remove the cover plate and unscrew the switch from the electrical box. Disconnect the wires from the old switch and connect them to the new switch in the same way. Screw the new switch back into the electrical box, replace the cover plate, and turn the power back on at the circuit breaker.

Turn the power back on and test the switch to ensure it is working properly.
You will want to leave about 8" of wire sticking out of the box. After connecting the light just push the extra back into the ceiling box.
Only if the existing switch box has an unswitched hot and neutral in it.

To install a light switch extension in your home, follow these steps: Turn off the power to the light switch at the circuit breaker. Remove the existing switch plate cover. Install the extension box over the existing switch box. Connect the wires from the existing switch to the extension box. Attach the new switch to the extension box. Secure the switch plate cover. Turn the power back on and test the new switch. Remember to always follow safety precautions and consult a professional if needed.

If you have one wire into your switch box for your light. this is called a switch leg, the dimmer should be wired across the black and white wire wires.
There are lots of diagrams on web under 3-way switch. However, the general principle is as follows. There are three terminals on each switch. One is the common and the other two can be used interchangeably. You connect the others together one for one between two switches. Then one switch common goes to supply voltage (Whichever box has the supply) and the other switch common goes to the load. Connect the supply white wire to the white wire in the light. If supply and load are in different boxes you will have to use one of the wires to connect together the neutrals between boxes. If they are both in same box you have to use extra wire to extend the common to the box where the supply and load do not exist.
