They certainly can. But they do not superimpose linearly as do most other waves, because the field equation is nonlinear. I believe there are known manifolds in which a collection of gravitational waves impinge on a region of spacetime such that a singularity and black hole form there.

As for all other types of waves, getting gravitational waves to cancel in a given region pretty much would require propagating waves from a single source over two different paths to the region in question (canceling everywhere is not possible). But the complex nature of gravitational radiation makes this MUCH more difficult than for EM or water waves.
