If items in a fireproof safe are purposefully set on fire with a fully closed and locked safe, are contents outside of the safe generally safe from fire?
The safe can be placed in a secluded spot and on stone.

Additionally, in general, what digital signals (if any, reliably) are able to penetrate a locked safe?
I assume you mean radio frequencies, and the answer is basically none. A grounded fireproof safe is basically a perfect faraday cage.
EDIT: Ok, I actually have a pedantic answer for this. If you put a microphone on a device inside the safe, you can signal it from outside by sending it vibrations, and you could encode a message in binary and thus technically send it a “digital signal”. If you wanted to be a little more analog you could use Morse code :)
Yes. Ok well that complicates things, but I suppose a piece of string small enough may be able to dangle out of the closed door and maybe be slightly moved…
