"Is Neha our friend?"
Translation:क्या नेहा हमारी दोस्त है?
Yes. दोस्त can be male, female, or plural. The only way to tell is from the articles (हमारी, हमारा, हमारे).
Not a pro on this, but I have noticed that when क्या is the first word in a sentence (question) it usually translates to "Is" or "Are". When it is the second it seems to mean "What". Weird I know...
In this sentence and others like it, it turns it from a statement ("Neha is our friend") to a question ("Is Neha our friend?").
It depends if it is a male or female friend. (See the reply on the first answer.)
