Mammals (class Mammalia) are group of vertebrate animals in which the young are nourished with milk from special mammary glands of the mother. In addition to these characteristic milk glands, mammals are distinguished by several other unique features. Hair is a typical feature, although in many whales it has disappeared except in the fetal stage. This ability to feed the offspring with milk occurs in whales as well.

Cetaceans, which is further split into Mysticeti, baleen whales, and Odontoceti, toothed whales, which includes dolphins, killer whales, and porpoises
Dolphins are in the group of marine mammals called cetaceans, specifically within the family Delphinidae. Within this family, there are different genera and species of dolphins, such as bottlenose dolphins, killer whales, and spinner dolphins.
A group of dolphins is called a pod. If that is your question.
Together, all the whales (as well as dolphins and porpoises) belong to a category of animal called cetaceans. I honestly think WHALES belong to the orcinus orca group. Not so. Orcinus orca is not a group, it is the official name of the killer whale.
