For example, is HSO4- (hydrogen sulfate) an acid? Is OH- (hydroxide) an acid?

Both of those are bases, not acids.
Add another hydrogen to HSO4- and you do get an acid, a very potent one : H2SO4 (sulfuric acid).
Add a hydrogen to OH- and you get water. Add another and you get an acid : H3O+, known as the hydronium ion. Which is a polyatomic ion, and an acid.
So the answer to your question is : "Yes, just not the ones you listed."

Yes, HSO4- is a bisulfate anion can donate its H+ in solution, but it's a fairly weak acid in comparison to the original H2SO4 (Ka value is much smaller). OH- by itself can't be considered a base, but many times compounds that dissociate to produce OH- can be classified as bases.
