If you are asking can you put a device, controlled by a switch, using a connection with an outlet, the answer is yes. The caveat is that whatever you add must stay within the amperage rating of the controlling fuse or breaker.
Simply run a wire from that outlet to that wall switch. Be sure you use the exact same wire size that you find in that outlet. It will be AWG 12/2 or 14/2. Do not mixes wire sizes. Connect the ground to green ground screw at outlet, and white wire to silver screw, and black wire to gold screw. At the light switch connect all white wires together under a wire nut and push them back into the box. Connect the ground wire to the green ground screw on the switch. Now connect the 2 black wires you have left, power in and power out, to the 2 screws on the switch. Does not matter which wires you connect to the 2 screws.
If the electrician that did the wiring was saving wire (preferable) the outlet closet to the fuse panel is the first one and the others downstream are further away. There is no absolute way to tell other than disconnecting one and see which others (downstream) are dead.
Yes
You can if you have a neutral wire present. If the existing switch is what is called a "switch loop" then you can not change the existing switch to a switched outlet. You can identify a switch loop by looking at the wires coming into the switch bow. If there are only one set of wires usually a black and white and they go directly to the switch then you have a switch loop
Home depot sells RF switches whereby if the fan is connected to the transmitter. It can be controlled by as far as 5 meters i believe In my SPA i have this device for safety. switch here get turn on there
No, that is not unsafe.
yes
You will need a receptacle that you can wire each outlet separately (not jumpered). You would then wire the switch in series on the line conductor with the outlet you want switchable. Wire the other outlet directly to the power source. You can jumper the neutral from one outlet to the other.
You need to run a wire from the existing power source to switch to switch to switch to outlet.
If there is a black wire going from the outlet to the switch and the other side of the switch goes back to the outlet then just cut these wires and connect supply wire directly to outlet. If the supply goes to the switch first, disconnect from switch and connect the two wires with a wire-nut. Some situations only switch one of the two outlets in a duplex device. Do the same thing, but also replace the outlet since the strapping between both outlets has been removed.
Yes you just have to "steal" power from the switch. Do this by running a pigtail wire from the hot of the switch to the hot wire of the plug. Make sure you do this before the switch or you will end up with your outlet being switched as well.

Sure. For a light you need a fixture to hold the light and the light itself. The light needs to be connected to a voltage supply which you can get from the outlet. In the outlet box you will have a black, white and bare ground wire. Essentially you connect the white and bare wires directly to the light and switch the black wire (hot) through a switch.
Yes
Bring power into the light switch box 12/2 or 14/2 wire depending on the existing wire. Make sure you use the exactly same size wire that is used on that circuit. If you do not know look at the breaker in the main panel that controls power to that circuit. 20 amp will be 12/2 wire and 15 amp will be 14/2 wire. Now run another wire from the switch box out to the outlet. Inside the switch box, strip both white wires back 3/4" and connect them together under a wire nut and push this back into the box. Connect the 2 ground wires together and then connect that to the ground screw on the switch. You now have 2 black wires left. Connect them to the 2 screws on the light switch. Does not matter which black wire you connect to which screw. At the outlet connect the ground wire to the green ground screw, black wire to copper screw, and white wire to silver screw. That outlet will now be controlled by the light switch.
Power into the first outlet and out to all other outlets, black to gold and white to silver screw, ground wires to ground screw. From the outlet closest to the light switch run power from that outlet up to the switch box. Run another wire from the switch box up to the light. In the switch box tie all the whites together under a wire nut and push them back into the box. Tie all the ground wires together and connect that to the ground screw on the switch. Connect the 2 black wires you have left to the 2 screws on the switch. Does not matter which if you only have power in and power out to the light.
