12-я панель не отображается, она только обновляет переменную до 11. Она должна показывать user_question после 11-й панели text_question. Так же user_question неправильно использует indexOf для определения целевого слова от пользователя.

Решение
У вас есть 6 вопросов с картинками и 5 текстовых вопросов.
Почему нет picture_questions(6);, но text_questions(6);?
Почему ваш ActionListener создать новый экземпляр партии? Это не нужно и сбивает с толку.
class click implements ActionListener{
public void actionPerformed(ActionEvent event){
party partier = new party();
....
}
}
Относительно вашего использования indexOf() метод для проверки пользовательского ввода: код будет работать, но вы проверяете пользовательский ввод во время создания фрейма, то есть задолго до того, как у пользователя появилась возможность ввести свой текст.
Цикл для проверки того, что пользователь ввел, принадлежит слушателю действия.
