The left-hand side of an assignment must be a context variable prefixed with either $, # or @# symbols.
When there is 3 symbols above, can I yet use "either"? if no, how can I say it?

You have used either correctly, but the sentence would be less ambiguous if you deleted it altogether:
The left-hand side of an assignment must be a context variable prefixed with $, # or @# symbols.
Collins Dictionary says, "You use either in front of the first of two or more alternatives, when you are stating the only possibilities or choices that there are."
