In the p shell, there are 3 orbitals in which electrons can exist: px, py, and pz. The subscript tells you how the orbital is oriented where px is located along the x-axis. The 2 in front says that the electron exists in the second level of the p subshell and in the first orbital.

They follow the order of the periodic table. Hydrogen and Helium are in the first row, and have electrons in the s-block. The next two elements in the second row are in the second energy level and fill the 2s shell. The next six elements in the second row fill the p shell. You list them in order of increasing energy. For example, for the element Chlorine, the full notation would be 1s^22s^22p63s^23p^5
I have a general question. The electron density distributions were illustrated for s p and d orbitals. What exactly do these show? For example, p-orbitals show 2 lobes on either side of the nucleus. Can electrons be found anywhere within the lobe on either side, or is it just on the border of these lobes? I'm just trying to gain a better general understanding of what this looks like conceptually.
