How do i remove this radiator

Close both valves. Use drain valve on left valve to drain radiator. Unscrew valves from radiator tails. Lift radiator off wall.
Don't forget that if you fit panels to the wall that will move the radiator out from the wall by the depth of the panel and anything behind it. So that may affect where the pipework will need to be to ensure the valves line back up to the rad when re-installed

If all you are doing is wanting to take the rad off then no need to drain the system, just the rad - Firstly - test the TRV on the right works properly. Put the CH on and turn the TRV all the way to 0. The rad should not heat up. That then ensures the TRV is shutting the rad off properly.
Then, leaving the TRV at 0, turn the hex in the valve on the left clockwise until it stops - that will mean the rad is then isolated from the flow and return. Then using the drain valve - the square lockshield to the right of the hex - to drain the rad down - opening the bleed valve at the top of the rad to speed that up. Once the rad is drained then the nuts at the rad tails can be undone and the rad removed.
Always best practice and sometime safer to have 2x1/2" blanks to cap off the valves either end until the rad is to be re-fitted.

No, as Madrab says above, turn it CLOCKWISE to close.

This varies by rad valve, and condition.
For a bit more reassurance at the thermostatic valve end, realise they operate by pushing a pin out when hot, to shut the valve.
If something is old they might still dribble, so you can help them by inserting a small disc of something hard at the point where it says "Pin".
Take the head off and see what fits. If you're lucky a small coin will go in, or cut up a hard plastic bottle cap. The valve will have rubber around where it says "insert" so don't tighten madly.

That's the bottom of the pin and is inside the valve. You won't get a coin in there
Alternatively, do it the prescribed way and get a decorators cap and remove the TRV head entirely.

To be fair, I think @Justin Passing was referring to using a coin in the plastic "maintenance" cap.
After the TRV crown has been removed I have had to use a pound coin in the generic cap to push the pin down. Icky, but I normally use my nicotine gum to hold the coin in place.
I also use gum to hold screws on to long screwdrivers when needs must.
Eh? I know what he meant but the diagram is wrong and can't be followed by a noob.
