potassium chloride
By "good" base, I assume you mean strong base. A generic strong base would be potassium hydroxide (KOH) or sodium hydroxide (NaOH)
To neutralise a strong acid, you would need a strong alkali (or lots of a weak alkali, but that would be impractical). Potassium hydroxide, sodium hydroxide, lithium hydroxide, calcium hydroxide, calcium hydroxide and magnesium hydroxide would all work.
It can be either. Two examples would be: Caustic soda (Sodium Hydroxide), which is very alkaline. Caustic potash (Potassium Hydroxide), which is very acidic.
I would guess that this is so because of potassium's mass, being much more than, sodium's molar mass per ion. So can sodium iodide be used instead of potassium iodide? Perhaps, but maybe not to the same level effectiveness. Potassium molecules have been known to dissolve better than sodium molecules. One example is Potassium Chloride and Sodium Chloride thanks
You would need to wear safety goggles, gloves, and a lab apron when working with potassium hydroxide.

It depends on the lab, but sodium bicarbonate, borax, sodium carbonate and sodium hydroxide (or their potassium equivalents) are popular alkalis with many uses.
Nothing
Sodium Hydroxide is way too basic (very high pH) and would cause internal damage.
Lye is one of those "common names" that, particularly when combined with adjectives, might mean a couple of different compounds. The canonical lye is sodium hydroxide. However, potassium hydroxide has very similar chemical properties, and I've seen terms like "wood lye" that indicate it's actually the potassium compound instead. "Caustic lye" is a new one on me; both compounds have common names that include the word caustic (caustic soda for sodium hydroxide, caustic potash for potassium hydroxide), so it might be either one. If it's in a recipe for soap or something, it doesn't really matter all that much; as stated earlier, they have very similar properties and either will work.
In most instances, sodium hydroxide is sufficiently close in chemical properties to potassium hydroxide to make each one a substitute for the other. There are some exceptions, however, and more details about the "activation process" under consideration would be needed to give a more detailed answer.

If it produces hydroxide ions (OH-) when dissolved in water, it is considered a base. Examples would be sodium hydroxide (NaOH), potassium hydroxide (KOH), and even ammonia (NH3) becauseNH3 + H2O ==> NH4+ + OH-

They aare used in order to absorb carbon dioxide.
