Мне нужно пройтись по всему объекту и сравнить id в массивах с сохраненными у меня в базе id и извлечь его, если оба id совпадают

Вы можете спарсить его в объект:

Gson gson = new Gson();
String jsonInString = "your_json";
YourJsonObject yourJsonObject= gson.fromJson(jsonInString, YourJsonObject.class);

А дальше уже спокойно сделать желаемое.
