The Earth formed 4.6bn years ago, and the temperature of the core is currently 5200°c, and it's projected to go cold in something like 90bn years time, which is irrelevant as the Sun will turn into a Red Giant in around 5bn years time, engulfing the Earth and completely destroying it, so to answer your question, it takes a VERY long time for the Earth to cool down- so long in fact, that it will actually NEVER cool down.
That would depend on what you consider "cool" to be. The world has been cooling almost since it first formed and it is still cooling today. So, there is really no answer to your question, unless you want to restate it to something like "how long did it take for the earth to cool to its current temperatures?". In that case, the answer would be the same as the age of the earth, or between 4 and 5 billion years.

That all depends on where you plan to start from. In my case for example, I am already there, so for me the time is short indeed.

Cookies typically take about 10-15 minutes to cool before they are ready to be eaten.
The amount of time it takes water to cool off would depend on the starting temperature of the water and the temperature of the environment. If it's cold in the environment, more than likely the water would take a short time to cool off.
It depends how long you're heating it.
I think that it takes about 1-2 minute to cool but I am not sure...
