well, your ques is grammatically wrong, but i fuigured you want to know different kinds of protists, but if you want to know ALL protists, that's just a bit too much for yahoo answers, because it is such a diversed group
Types of protists

Protozoa, the animal-like protists
Protozoa are mostly single-celled, motile protists that feed by phagocytosis, though there are numerous exceptions. They are usually only 0.01–0.5 mm in size, generally too small to be seen without magnification. Protozoa are grouped by method of locomotion into:

Flagellates with long flagella e.g., Euglena
Amoeboids with transient pseudopodia e.g., Amoeba
Ciliates with multiple, short cilia e.g., Paramecium
Sporozoa non-mobile parasites; some can form spores e.g., Toxoplasma


Algae, the plant-like protists
They include many single-celled organisms that are also considered protozoa, such as Euglena, which many believe have acquired chloroplasts through secondary endosymbiosis. Others are non-motile, and some (called seaweeds) are truly multicellular, including members of the following groups:
