[Are they all grammatical? Can we use both 'into' and 'in' in this case? Which ones are commonly used?]

Answer 1

They are all correct. "got into" implies there might have been some difficulty, as if she had to crawl through a window or break down the door. "I had to break a window, but I got into the burning house to rescue the dog." "walked into" or "went in" implies normal circumstances.
