No. The SKS fires a 7.62x39 cartridge, but actually uses a .311 bullet. The 7.62 x51 is too long for the SKS action, the chamber of a SKS is too short for the cartridge, the power of the 51 is too high for the SKS action, and the bullet of the 7.62x51 is actually .308, not .311. Does not match up in any way.
No. PA does not require gun registration- and the SKS is not an assault rifle- it is a semi auto rifle with a fixed magazine.

No, the two numbers are clearly different. In a more practical note, "7.62" is the diameter (in millimeters) of a bullet typically fired from a .30 caliber rifle such as a Chinese SKS or Russian AK-47 rifle, while "5.56" is the diameter (in millimeters) of a .223 caliber bullet like the M-16 or AR15 rifle.

Mikhail Kalashnikov designed the AK47 rifle. If, at any point, he had designed it for a larger cartridge (which there is no indication that he did), then it would have been because he had begun the design before the requirement was made that his design utilize the 7.62x39 cartridge, which was first used in the SKS rifle.
Plenty available.
