Based on color patterns on the body and the distinctive dorsal fin patterns (nicks along the trailing edge of the fin), my best guess is that there were four adults and one calf. See what you think:
Here's one shot with Dolphins 2 and 3 side-by-side:
And, the calf! Head-first:
Then the calf rolling, showing its smaller dorsal fin:
The calf stayed closest to Dolphin 4. That's the one that just surfacing in the photo above and the grayer individual in the photo below:
One more (not sure which individual this is):
The dolphins were headed south, perhaps starting to round Bodega Head towards Doran Beach. If the ocean stays calm, it could be good conditions for dolphin-watching. Let me know if you see them!
P.S. I'm hoping Bill might be able to help identify these dolphins (if they are known individuals and where they were last seen). If so, I'll update this post.
