All salt is kosher unless something is added to it to render it not kosher. If the question is in regard to kashering salt, the salt used to kasher meat, that product is not suitable for cooking as it is an extra coarse salt that does not dissolve well.
Kosher salt is sodium chloride.
Non-kosher pickles usually have the same ingredients that kosher pickles do only they're not made under kosher supervision and the ingredients used (vinegar mainly) might not be kosher.
yes !
Everything that grows from the ground is kosher. Concerning the pickles only, there's nothing in a pickle that makes it non-kosher, as long as it doesn't come in contact with other ingredients, or machinery, used in non-kosher products. But just like anything else on the supermarket shelf, one has to check to make sure. Kosher pickles should be kosher. To confirm this, you would need to check the labeling for a recognized hechsher (kosher certification symbol). The US, and most other countries with food labeling laws, doesn't allow any reference to being kosher unless the product is certified kosher. Pickles that are labeled "kosher style", are most likely not kosher. Items that could render pickles not kosher are primarily non-kosher spices and non- kosher vinegar.
All salt is kosher. "Kosher salt" is a particular grade of salt, with coarse crystals, that is used for making meat kosher, and is also useful in cooking. It's no more kosher than any other kind of salt.
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. Quick salt is another name for saltpeter, or potassium nitrate: among other things, it's used for making cured meats like salami. Kosher salt is made of sodium chloride like regular table salt, but has larger grains and is used to draw blood out of meat in order to make the meat kosher (hence the name).
Most salt is kosher by default unless additives such as flavourings are added, at that point the salt would have to be certified kosher. 'Kosher salt' refers to a large grain salt that is used during the process of kashering meat. Iodized salt is kosher.
No, it is not. Almost all mass produced salts are considered kosher and have been certified kosher by a rabbi or authorized organization. Kosher salt gets its name from from what it was originally used for. Kosher salt is much larger grains and was used to pull the blood out of meats so that it meets the Jewish guidelines. That process is often referred to as "koshering" and that's where kosher salt got its name from. But any salt that is certified free of additives can be certified kosher and used.
Regular table salt.
