здесь не нужна итерация по словарю, можно же просто
name = student_dict['first_name']
остальное ок

видимо эта ошибка идёт через все задания :)
это кстати именно ошибка, потому что может привести к неожиданному поведению, например если структура student_dict расширится вот таким образом
{'first_name': 'Вася', 'mother_name': 'Галя', 'father_name': 'Вася', 'pet_name': 'Вася'}
| counter_student_name_max[name] += 1 | ||
| else: | ||
| counter_student_name_max[name] = 1 | ||
| name = sorted(counter_student_name_max.items(), key=lambda item: item[1], reverse=True) |

как вариант, ещё можно использовать max(), он тоже умеет с аргументом key

Вообще это законно, но я бы предложил возвращать просто name_student[0][0], а весь пост-процессинг делать за пределами функции. Таким образом мы немножко улучшим чистоту кода.

ага, здесь тоже просто по ключу берём из словаря то, что надо, цикл не нужен
