This is how you can handle the response message I am handling for error 500 you can add as much you want

                switch (response.code()) {
                    case HttpURLConnection.HTTP_OK:
                        break;
                    case HttpURLConnection.HTTP_UNAUTHORIZED:
                        callback.onUnAuthentic();
                        break;
                    case HttpURLConnection.HTTP_INTERNAL_ERROR:
                        try {
                            String errorResponse = response.errorBody().string();
                            JSONObject object = new JSONObject(errorResponse);
                            String message = "Error";
                            if (object.has("Message"))
                                message = String.valueOf(object.get("Message"));
                            callback.onError(message);
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                        break;
                    case HttpURLConnection.HTTP_GATEWAY_TIMEOUT:
                    case HttpURLConnection.HTTP_CLIENT_TIMEOUT:
                    default:
                        callback.onNetworkError();
                        break;
                }
