There are about 60,000 different species of the protists. Protista is one of the five kingdoms of organisms.
Yes, plankton can include protists. Protists are a group of diverse eukaryotic organisms that do not fit into the plant, animal, or fungi kingdoms, and many species of plankton fall under this category.
Protists play many roles in nature such as decomposers, photosynthetic producers, disease causing pathogens, mutualistic symbiotic relationships with other species, and many other roles.
The only organisms that like to eat protists that I have heard of are other species of protists and people fond of Japanese cooking.
One kind of organism is a species.

There are almost 800 species of Euglena currently known by scientists. This contains approximately 44 genera. Euglena is a genus of unicellular protists.
Protists belong to the kingdom Protista. As Protists is a diverse group, it can further be classified into various phyla, classes, orders, families, genera, and species depending on the specific organism in question.
Protists can be either sessile or motile, depending on the species and environmental conditions. Many unicellular protists, such as amoebas and paramecia, are motile, using structures like cilia, flagella, or pseudopodia to move. Conversely, some protists, like certain algae and diatoms, are sessile and may attach to surfaces or float in water. Overall, their mobility varies widely within the diverse group of protists.
Protists only have one cell.
