Answer 1

Robert Harding Whittaker was the first to propose the five-kingdom classification of all organisms into
Animalia, Plantae, Fungi, Protista, and Monera in 1969.

according to this classification 
bacteria come under the kingdom Monera
protozoa : subkingdom of the kingdom Protista
algae :  Kingdom Plantae
prokaryotes : Monera
eukaryotic : eukaryotic kingdoms are animalia, plantae, fungi, and protista.
thesecare multicellular animals ...and they are in more than one kingdoms !
