Can I replace this broken pipe under my kitchen sink?

Yes - that's a "tailpiece" - the new one may be too long, if so, they are made that way so you can cut them to fit - but there's also considerable space to slide them built into the connections, so ...

In order to avoid shutting off water to the whole house, can I temporarily terminate a PEX pipe at a closed shut-off valve?

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.

You are correct - that's a glued trap which are much more of a pain to work with than slip-joint traps, since there are less places to take them apart. The clear pipe from the dishwasher should loop ...

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.
