Answer 1

внутри метода GraphRequest

GraphRequest request = GraphRequest.newMeRequest(
           loginResult.getAccessToken(), 
           new GraphRequest.GraphJSONObjectCallback() { 
            @Override 
    public void onCompleted(JSONObject object,GraphResponse response) { 
     object.getString("first_name") 
    } 
}); 

Answer 2

Это многомерный массив, так что вы первый пролил этот массив.

String res="["+"{responseCode: 200, graphObject: {"id":"108303252910226","first_name":"Chris","last_name":"Jack","email":"adaptech123@gmail.com","gender":"male","birthday":"08\/08\/1984","hometown":{"id":"106377336067638","name":"Bangalore, India"}}, error: null}"+"]"; 
      JSONObject c; 
      JSONArray data=null; 
      try { 
       data = new JSONArray(res); 
      } catch (JSONException e1) { 
       e1.printStackTrace(); 
      } 
     try { 
     if(data != null) { 
       for (int i = 0; i < data.length(); i++) { 
        c = data.getJSONObject(i); 
        String lat=c.getString("responseCode"); 
        JSONArray dd=  c.getJSONArray("graphObject") 
         } 

then json encode with dd string.
