She is in English classroom
I am not sure if this expression actually exists.
She is in English classroom. When someone asks you this: Where is she?

You need an article for "classroom".
So either:
She is in the English classroom.
or
She is in an English classroom.
"Class" does not need an article so you could say:
She is in English class.
That would probably be a more natural way of expressing the concept, if she was in the room while the class was going on. It would not be wrong to use an article in the last sentence, but you do not have to, and most native speakers wouldn't except to emphasize whether it was "the" or "an" English class.

Classroom = the room where the lessons are taken.
English class = English lessons.
