No, they are equivalent.

No, the same amount.
Yes, you can use regular salt instead of kosher salt in the recipe, but you may need to adjust the amount used as kosher salt has larger flakes and is less dense than regular salt.
Table salt and kosher salt are both 39% sodium by weight.
Kosher salt is the same as table salt, just larger granules. Sea salt has less sodium than table salt as the mineral makeup is different.
To substitute regular salt for kosher salt in a recipe, use half the amount of regular salt as the recipe calls for kosher salt. This is because kosher salt has larger flakes and takes up more space than regular salt. Adjust to taste as needed.
Yes. "Kosher" salt is really a misnomer. Coarse salt was used to cure and preserve certain meats, by drawing out residual blood, part of the process of "koshering" meat. So it came to be known as "kosher" salt, when if anything it should be called "koshering" salt. But because kosher salt is like lots of regular salt crystals stuck together, if the recipe calls for regular salt you need to use less kosher salt, but if the recipe calls for kosher salt you will most likely wind up needing more regular salt if you don't have kosher salt handy.
Any difference, both are sodium chloride (NaCl).
Almost all salt is kosher by default. The only issue would be if non-kosher additives such as flavourings were added to the salt. Sea salt is healthier than traditional table salt as the sodium level in sea salt is far lower.
No, kosher salt is identical in mineral content to table salt.
Kosher salt is sodium chloride.
"Kosher salt" is chemically the same as regular table salt, sodium chloride. It's not that the salt itself is kosher (it is, but so is just about any pure table salt). It's really more "koshering salt" ... suitable for use in salting meat to make it kosher (by removing the blood). Kosher salt is usually physically, not chemically, different from regular table salt. The grains tend to be larger and in the form of flat flakes rather than tiny cubes. Kosher salt usually contains no additives such as iodine (regular table salt is often sold with added iodine, usually labelled "iodized salt").
