I will try to dig up additional info. I know that nightfighter ace Wolfgang Schnaufer did fly almost exclusively Bf110. And for the most time of the war, he was accompanied by his
Bordfunker (=radioman) Fritz Rumplehardt and his
Bordschütze (=gunner) Wilhelm Gänsler, both of them eventually decorated with the Ritterkreuz. That would make three...
EDIT:
All my book credit the 110 radar equipped night-fighter versions with 3 crewmembers. But as we know, sometimes they just copy each other, so I googled just a bit and found this:
"One night, after detecting an unsuspecting Lancaster in the bomber stream, into which he (Martin Drewes) mixed up thanks to Erich Handke (his excellent Bordfunker, or radar-operator, Ritterkreuzträger, or Knight's Cross bearer, in German), he proceed to make the conventional Schräge Musik attack, right from below, spreading the these guns fire from the inboard left engine till the starboard one ((...) The bomber disintegrated, and took Drewes and its crew with it, through an incredible amount of debris, which dilacerated the Bf-110G-4 (G9+MD)...they all had to jump immediately for their lives from the plane's blazing hulk!!! One schrapnel hit the gunner's (Oberfeldwebel Petz) wristwatch, stopping it right at the moment of the explosion: 01:19hs..."

Once again, 3 crewmembers in a Bf 110.
