This is kind of tricky. Krill are actually small shrimp, but capable of purposeful swimming. Plankton, by definition, are all the little things in the water, some plants, some animals, that are not capable of purposeful swimming. That is, even if they swim a little, it is not enough to move them significantly from place to place relative to ocean currents. Larval krill would be part of the planktonic community, as would the larvae of many marine creatures. But adult krill are not plankton.

Size comparison: Krill can grow to over 20cm in length and feed primarily on the mostly microscopic plankton.

No, they are tiny shrimp-like crustaceans, less than 1 inch (2 cm) in length. They strain tiny plants from seawater to eat, and are eaten in turn by larger sea creatures such as fish (and mammals, in the case of whales).

Phytoplankton are any plankton that are photosynthetic. There are non-photosynthetic plankton that are animals, bacteria, or archaebacteria.
