Lead has 82 electrons. It also has four valence electrons, two s- electrons and two p- electrons in its orbitals.

All three 2p orbitals (2px, 2py, 2pz) are occupied by two electrons each.(6 electrons in total: (2px2, 2py2, 2pz2) = 2p6)
Twelve: 6 electrons in 2p6 and 6 electrons in 3p6. No electrons in 4p orbital in ground state, so 4p0, only 4s1 is occupied (4th period, group 1)
2
Multiply the orbitals in that sublevel by 2. The s sublevel has one orbital and can contain 2 electrons. The p sublevel has three orbitals and can contain 6 electrons. The d sublevel has five orbitals and can contain 10 electrons. The f sublevel has seven orbitals and can contain 14 electrons.
zero - after the 4s orbitals are filled at Calcium, the 3d orbitals start to fill - not until Gallium do the 4p orbitals start to fill.

1 inn the outer shell; Al has an electronic configuration of [Ne] 3s2, 3p1. In level 2 all three of the 2p orbitals are occupied by 2 electrons making 6 p electrons at this level. In total Al has 7 electrons in p orbitals.
Sulfur has two electrons in the 1s orbital, two electrons in the 2s orbital, and 6electrons in the 2 p orbitals. The electrons are part of the first and second energy levels, the electron core. The next energy level, the last one, is the outermost energy which comprises the valence shell.

Ne has three p-orbitals.

[Ar]4s13d5 why is it arranged in this way is simply because a fully occupied is more stable than half occupied and partially occupied at last.
5 electrons in p orbitals in the outer shell. Cl has an electronic configuration of [Ne] 3s2, 3p5 In level 2 there a further 6 electrons in p orbitals making 11 electrons in total occupying p orbitals
Multiply the orbitals in that sublevel by 2. The s sublevel has one orbital and can contain 2 electrons. The p sublevel has three orbitals and can contain 6 electrons. The d sublevel has five orbitals and can contain 10 electrons. The f sublevel has seven orbitals and can contain 14 electrons.
In theory all elements have all the orbitals. Zinc has electrons in four of them.
