Alternative method for connecting sink drain with waste pipe directly under?

What adhesive is typically used to "glue" a porcelain under-counter sink to a stone countertop

Most likely it's silicone. You should be able to cut it with a razor/knife to free the sink and then scrape/peel it off completely once the sink is out of the way.

How can I unscrew this nut with little clearance?

File a bit of steel pipe so that you have two pins that match the notches in the nut - this will lengthen the nut to a point where you can apply normal tools.
