Weird question maybe but how many is Zorjá? 1,2 or 3?
It's not weird! The answer, however, is all of the above.
When it comes to our original sources, they are described as all three with pretty equal variation, so you can not really say there is any original version.
If Zoria is depicted as one, she is usually Zoria Svitova (you may see it as Zorya Utrenniaya and many other versions - those are all words for "Morning Star" in Slavic languages). If two, it is Zoria Svitova and Vechirnia, the Morning and Evening Stars. If three, it is Zoria Svitova, Vechirnia, and Polunochna, adding the Midnight Star.
When multiple, the Zorias also tend to have opposing personalities.
You have a few options here - either make a decision that makes sense for your practice, or adjust as called for in the situation. Neither answer is really wrong.
Personally, I see the Zoria as one and three.
