It depends. Baleen whales, such as blue and humpback feeds on krill, plankton, and small fish and squids.
Tooth whales , such as sperm and belugas, will feed on fish, squids, crustaceans,etc.
The killer whale or orca is the only known cetacean that will include other marine mammals, such as seals, sea lions, dolphins and large whales, and sea birds in their diet

Way too general. But, I can help make it more specific.
There are two basic types of whales based on their teeth structure. There are the toothed whales (Odontoceti) and the baleen whales (Mysticeti).
The toothed whales all have teeth. They (including dolphins, killer whale, porpoises, grampus, pilot whales, narwhal, white whale, river dolphins, sperm whale, and pygmy sperm whales) eat anything small enough for them to kill and big enough for a meal.
The sperm whale is the largest toothed whale. It eats very large animals, including the giant squid.
The killer whale attacks in groups. A group of them will kill larger whales. They are extremely dangerous mammals, though generally docile around people.
Dolphins and porpoises generally eat fish. Marine dolphins are very dangerous to sharks. They are good at protecting those people that keep them, and will not tolerate sharks' intrusion. Dolphins are very fast, and will actually kill sharks by ramming them with their hard beaks.
The baleen whales do not have teeth. Instead of teeth, they have plates of baleen. They use the baleen plates to siphon their food. The food is always plankon and tiny fish.
Baleen whales include the humpback whales, right whales, rorquals, and the blue whale (sulphur-bottom). Most of these are even bigger than the sperm whale.
An interesting fact: Many of the large baleen whales often have barnacles attached to their bottom. Barnacles are tiny, primitive crustaceans that attach themselves to ships, whales, and anything really. Barnacles become sedentary, never moving from one spot.

Depends, If it is a baleen type whale( whales with a filter in their mouth) they eat krill and plankton.
If it is a toothed whale, they hunt anything from large fish to seals and squid.
