Looking at the electron configuration of carbon (at. no. 6) you have 1s2 2s2 2p2. In the 2 p subshell, you have 1 electron in the 2px orbital, and 1 electron in the 2py orbital and no electrons in the 2pz orbital. So, the answer is that there are TWO half filled orbitals in the carbon atom. This is the case BEFORE hybridization. After hybridization, there are FOUR half filled orbitals which are called sp3 hybrids.
Carbon is the sixth element with a total of 6 electrons. In writing the electron configuration for carbon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for C goes in the 2s orbital. The remaining two electrons will go in the 2p orbital. Therefore the C electron configuration will be 1s2 2s2 2p2.
The charge of an electron is always −1.602176487(40)×10−19 Coulomb. If an electron is ejected from it's orbital the energy it absorbs is in the form of kinetic energy i.e. how fast it moves. If the electron goes back into an orbital it will only be allowed in an orbital that allows for it's energy. If an atom has an electron and that electron absorbs the energy from an incoming photon it may jump up to a higher orbital or it may be ejected. The ejected electron is the principle of the photo-electric effect.
The element Lithium has a total of three electrons. The first two electrons would be placed in the 1s orbital. Then the third electron would be placed above the first two, in the 2s orbital. Because Lithium Ion has a +1 charge, one electron would be missing. So only the 1s orbital would be full.

A spherical electron cloud surrounding an atomic nucleus would best represent an s orbital. A maximum of 2 electrons can occupy an orbital.

The electrons fill each of the five orbitals, so there is 1 electron in each of the five orbitals. Then the 6th electron would pair its spin with the first orbital, the 7th would pair its spin with the 2nd orbital, etc.

It depends on the atom. For example, the electron configuration of an atom of boron in the ground state is 2-3. In the excited state, it would be 2-2-1. For an atom of chlorine, the ground state configuration is 2-8-7. The excited state would be 2-8-6-1. When an atom enters the excited state, an electron moves up to a higher energy level and releases energy. An electron in the excited state is not stable until it returns to ground state.

That would be the electron cloud. This is like the orbital model where there are electrons in each orbit level but the electron's location can not be predicted so it is said to be most likely at a point in the electron cloud.
To draw the orbital diagram for hydrogen with an atomic mass of 3 and atomic number of 1, you start by writing the electron configuration as 1s1. Since hydrogen has only one electron, it occupies the 1s orbital. The orbital diagram would show a single electron in the 1s orbital, depicted as ↑.
If the electron were the size of a golf ball, the proton would be about the size of a basketball and the electron would be orbiting about 8000 meters away (assuming the Bohr model of the atom).
