If your unable to figure out how to work a compass its probably best not to use it.
No, a traditional compass would not work at the center of the Earth because it relies on the Earth's magnetic field which would be disrupted by the extreme heat and pressure at that depth. Additionally, at the center of the Earth, gravity would be pulling equally in all directions which would affect the accuracy of the compass needle.
a compass can be used anywhere.... the accuracy however may suffer in the magnetic polar regions. Then of course there is outer space where a compass would not work
Yes, a compass works best when it is close to a magnet because the magnet helps align the compass needle with Earth's magnetic field. The closer the compass is to a magnet, the stronger the magnetic force acting on the needle, making it easier for the compass to point in the correct direction.
A magnetic compass depends on Earth's magnetic field for orientation. In space, there is no magnetic field to interact with, so a magnetic compass would not be useful for navigation. Other orientation systems, like gyroscopes or star tracking sensors, are used instead in space.

The compass indicates the direction of magnetic North, from that you can work out South, East, West and all the other points on the compass.
No, a compass may be unreliable underground in a mine due to interference from the surrounding metal ores and rock formations. Magnetic fields can be distorted and may cause the compass to give inaccurate readings. It is best to rely on other navigation tools in such environments.
Though it would be much easier to use a modern-day compass, you could use an ancient Chinese compass if you have a working one. Most compasses from ancient China would have had to be well preserved to work. Maybe it does work, but it would probably be inaccurate because of it's age. If it is in complete working order (you could probably go to a well reviewed pawn shop to tell if it works or is accurate) then yes, you could still use it. Not many people do, though. You could buy some that supposedly work on E-Bay for $700. YIKES!
No, he used one and the world in general was much more advanced than that in 1492. Nor did they think the world was flat.
Yes, you can use a compass on the moon. The principles of magnetism that a compass relies on would still work on the moon. However, the moon does not have a global magnetic field like Earth, so the accuracy and functionality of a compass may be limited.
