Do all questions have answers?

Quaerendo invenietis (?)

Nope. Some don't have answers because they are meaningless:

Why do colorless green ideas sleep furiously?

Some don't have answers because they cannot have answers---not even in principle:

What's the largest even number?

Some don't have answers because they are rhetorical:

How many roads must a man walk down before you can call him a man?


Some don't have answers because it's practically impossible to answer them:

How many atoms comprise the earth's atmosphere right now?

There's probably other examples?
