I assume you know it's generally safe to round to modern values.
C3, I'd probably use .022, this couples audio into the first amplifier stage, higher value=stronger bass, so may as well use the biggest the engineers saw fit to use.
C5 I think is a feedback capacitor? Probably another .022, remember that anywhere they used paper caps isn't terribly critical.
33 and 47 (or better yet 68, old electrolytic caps were usually toleranced at -20%, +80%, so you can safely go up a bit) for the B+ filters, also go up on the voltage rating as often old stuff ran near the limit. Higher voltage rating also often means a larger, higher ripple rating, cooler running, longer life part. It is possible to get into trouble there with considerably smaller modern capacitors running hot.
