I know there would be three connections between the cab and first trailer but what about the dolly and second trailer? Are there the same three at both the dolly and the second trailer?

Yes, you will need a electrical cable pin connector to run any lights, a service air line, and a supply air line.
Check out the Generic Air Brakes & plumbing within this forum topic group "towing trailer and converter dolly". Same setup on a newer style booster. Now, if you have a steerable booster, you will need hydraulic lines as well.
