1/6 g should do okay for pretty long stays. It may require a heavy exercise
schedule.

Two days transit. No problem, unless you run into a major solar storm with no
shielding.

Right. Not that short stays will need any more shielding than the landing
module provides.

How much regolith do you need to emulate the shielding Earth's atmosphere
provides? 1 m, maybe two.

Hello? You seem to think we're doing lunar mining here?

If you're deep, a leak is no problem: material shields. Patching from the
inside as well: polymerizable monomer in situ. Leaks will happen (everything
we sent up to LEO has been leaking like a sieve) but there
are enough volatiles to replenish the losses on Luna.
