The entropy of a contracting universe is a bit of a mystery. Try reading Hawking's Brief History of Time.

But the current evidence is that the universe will expand forever, so entropy will keep increasing. (And it appears that we are not in a cyclic universe of expansions/contractions & multiple Big Bangs. Other universes are pure speculation.)

The entropy of a black hole still increases. Although it temporarily becomes ordered, the black hole eventually evaporates into disorder.
