It's not impossible, but given that Orcas eat most of those species pretty ruthlessly I'd say it's unlikely. But who knows, maybe it's a fish eating resident pod and not a mammal eating transient pod, and whales aren't racist?
Whales can actually tell if it's a fish eating or mammal eating pod and treat them accordingly. Off the coast of Newfoundland, there's both mammal-hunting pods which are universally shunned by other cetaceans there and fish-eating pods that have specialized in hunting cooperatively with humpback whales using the technique of bubble-netting herring swarms. Cetaceans like narwals that would be the prey of the mammal-eating pods do not flee these orcas. Orca pods both settle on one lifelong hunting strategy that they almost never change and each pod has an individual accent, so a sufficiently intelligent species can identify if they're a threat if they are locals by listening to them. Given how fine cetacean hearing is, they probably know who they're dealing with long before the orcas themselves can be "seen" because they are within effective sonar reach.
Interspecies cooperative hunting is also known from Pesudorca crassidens, who often forms pods of hundreds or thousands of individuals with other dolphin species such as spinner dolphins. They're also know to regularly have both gay and straight sexual relationships with these. :pseudorca:
