ANSWER - It is possible to grout over existing grout if there is enough depth to do so. 1/8 inch depth may or may not be adequate depending on the type of grout used. A latex modified grout may work, but you have to properly clean the existing grout to ensure the new grout adequately bonds.
Yes. It should bond well assuming 1) the grout is still clean, and 2) you clear the surface of dust and debris. However, if the depth you're filling is extremely shallow, you may be better off in the long term by grinding most of the existing grout out first.
But yes, you can wet it (lightly) and go over it again with more grout, even if it is unsanded. Once you get it filled properly and it's allowed to cure the unsanded will work fine, it's just a LOT more work to fill, let it cure (shrink), fill again, etc. Once filled and cured the stability is the same as sanded grout.
Yes you can touch up grout however, you only want to touch it up or refill areas that it is absolutely necessary. Otherwise you will have patches of grout all in different colors. Even if you have the correct grout (fading, and travel) zebra pattern will look terrible... good luck!
