return new Status("success", cursor.toString());

You are returning cursor.toString() which is cursor's string representation, which doesn't read content of cursor rather use cursor.next() as you have used in loop.

Create list of status and add status into this list one by one and return list, please see below code:

try {           

    //Build the query
    BasicDBObject query = new BasicDBObject();                                              
    query.put("building_Id", building_Id);
    query.put("floor_Id", floor_Id);

    DBObject removeIdProjection = new BasicDBObject("_id", 0);

    //Provide the query as an argument to the find()
    DBCursor cursor = col.find(query, removeIdProjection);          
    List<Status> statusList = new ArrayList<>(); 
    //Iterate the cursor
    while (cursor.hasNext()) {
        Status status = new Status("success", cursor.next()); 
        statusList.add(status);
    }

    return statusList;

} catch(Exception e) {
    e.printStackTrace();
}
