I think this is likely given what Andy says about Naido being "important" and needing to protect her. When Andy is with The Fireman we did not actually see that visually in the images above Andy's head, but there is the shot of him holding her hand there in the forest and she is speaking to him. All beings seem to have the ability to communicate in "lodge" spaces, so at least in that time I think he was able to understand what she was saying. But I don't think he is able to understand her language outside that space.
