Organism.
Yes a cell can be a living organism - but it would have to be one that can live by itself, performing all the functions of life, in which case it is a unicellular organism. Prokaryotes are excellent examples, with things like amoebas, bacteria (such as E.coli) etc.
No, an organism with one cell is uni-cellular.
No. A brain cell is just one cell in a many-celled organism.
it would be a organism.

An elodea cell is part of a larger being, it cannot survive on its own, it only contains part of the thing a plant needs to live. Paramecium do live as only one cell, a fully functioning organism.
An organism that has only one cell.
