0.5 lead may or may not be equivalent to a #2 pencil. #2 refers to the hardness of the lead, while numbers referring to mechanical pencil leads such as 0.5mm and 0.7mm refer to the width of the lead. 0.5mm lead will be finer and likely more prone to breaking, but can allow much finer lines to be drawn. 0.7mm lead will usually be slightly more resistant to breakage, but will have thicker lines.
The # is reference to the hardness of lead A number 2 pencil is averagely hard aka HB
The "number 2" designation refers to the "hardness" of the lead. The higher the number, the "harder" The "7mm" designation refers to the "thickness" of the lead. The higher the number, the thicker. They are not the same pencil.
The number of the pencil is based on the type of carbon lead used inside. The thicker the carbon lead gets the higher the number of the pencil becomes. If you notice a mechanical pencil is 0.9mm in diameter so it would be called a #0.9 pencil. A #2 pencil's lead is 2mm in diameter. So Why would we call a pencil a #3 pencil? Because it's lead is 3mm in diameter.
Actually, what you are asking is referring to the hardness of the pencil. So both, 0.5mm and 0.7mm are the same hardness as number two pencils. The number of lead, 0.5, is a thinner lead in diameter to the 0.7.
The number two in reference to a pencil denotes the relative hardness of the graphite or "lead" that is in the pencil, HB being softer and three being harder, etc.
The 2 is the number of the lead in the pencil.
Yes!!!

number 2 describes the thickness of the lead, and darkness of the lead

It has to do with the kind of graphite or material used as the lead for the pencil.

Owning both 05 and 07, 05 is thinner. It is more prone to breaking. I have resorted to purchasing only .07 mechanical pencils. And my wife recently brought me a box of mark sense lead, that is only about 2 inches long, but appears to be .144 lead - it does appear twice as thick as .07 - now if only I can find a pencil that uses it!
i like to use a good lead pencil number 1 because the lead isn't as hard as a number 2 pencil and therefore is easier to shade with. Good luck with your drawing!
To dissolve pencil lead from the skin, place the pencil in a container of H2O2 and it should dissolve in a day or 2.
