I have an old pair of speakers whose foam grilles turned to dust.

Can they be replaced with any old thing? Or must I obtain special

And how difficult is this stuff to cut?

Foam of any type is very difficult to cut neatly. Best way (if possible)
would be to use a proper speaker fabric. You'll find it on Ebay, etc.

The foam rectangle would be inset into the surround of the speaker. As I
recall, the original had square edges and nestled in reasonably
securely.

If I were to use speaker fabric, I'd also need to create a frame that I
could fit into the surround. Foam sounds easier, if not as attractive.
