If you mean move around in "orbit" around the nucleus ...
They don't. In quantum mechanics, forget everything you know from everyday experience about how objects behave, because quantum mechanics is WEIRD. One of my teachers once told me "nobody ever really understands quantum mechanics, they just get used to it." There's a fair amount of truth in that statement. Trying to picture it in your mind will only get you so far; at a certain point you just need to do the math and trust what it says even if it doesn't make any sense.
The region of an atom in which the electrons move is called the electron shell, or electron cloud.
The excited electron move up.
The electron has the speed of light.

Electrons move around the nucleus of the atom.
Only the free valence electrons forming the electron "gas" move and as many move in as move out. Only metals form this electron "gas".

No, electrons move in a circuit in a continuous flow called an electric current. Electrons move from the negative terminal of the battery, through the circuit components, and return to the positive terminal. Each electron only moves a short distance within the circuit before passing its energy to the next electron.
The region of space where electrons of a certain energy move about the nucleus of an atom is called an electron orbital. Electron orbitals are regions where there is a high probability of finding an electron based on its energy level. Different electron orbitals have different shapes and orientations.
The amount of energy needed to move an electron from one energy level to another is known as the energy difference between the two levels. This energy difference is typically quantified in electron volts (eV) or joules.
