Yes, for

does anyone know if e.g. apollo, the achaeans &c are thought to have had the digamma.

No on all of these (Apollo hardly needs more metrical strangeness). You can find a good list in Seymour, section 14 (page 45 of the book; not sure exactly what page of the PDF).
The problem with digamma is that whoever composed the Iliad and Odyssey was probably working from memory of how certain words behaved in older recitations. Sometimes the verses act like the digamma is present, sometimes not. Strangely, Hesiod, who almost certainly spoke a dialect that preserved the digamma, used it
less than the monumental poets. Perhaps he was trying to sound more Ionic, less bumpkin. No one knows for sure.
