PS Не забывайте про вспомогательный глагол - DID (+ VI) - когда задаёте вопрос в Past Simple (Indefinite)

2. You likeв his new book, didn't you? Имхо, такой вариант точнее передаёт оттенок вопроса.
11. Я б использовал в обеих частях вопроса Present Perfect, поскольку в самом предложении (что в одном, что во втором) явно не указано, к какому времени относится вопрос (в отличие от всех других примеров) . А действие к настоящему моменту явно завершено.

2. You liked his new book, did't you?. -No, I did't.
7. How many letters did you type yesterday?
11. When did he come back from St. Petersburg?- A week ago
How long did he stay there? ( How much time did he spend there - это дословно, но не очень по-английски)

6. Did you look through these documents yesterday?
7.How many letters DID you publish (type-набрали на комп. ) yesterday? -
I published 12 letters (12 of them)
11. When DID he return (come back) from St. Pet.?
How long had he been there? He had been there for 5 days.

7. How many letters did you publish yesterday ?.
11. When did he return from St. Petersburg - A week ago. - How long did he be there? - Five days.
Меня тоже потянуло не перфект, но A week ago не позволяет.

1. Я бы поставила used to live.
2. You did like ...didn't you? (=ведь)
5. Did he actually work... (если в интонации сомнение)
7. How many ...did you type yesterday? Publish - публиковать в основном.
11. When did he return...?How long had he been staying there?

7 и 11 с ошибками
7. How many letters did you publish yesterday?
11. я не знаю, но я бы оставил past simple, несмотря на то что не указано время прямо тут, здесь указано место, ..во втором предложении в принципе можно и past perfect
When did he return from St. Petersburg?
How much time (How long) had he spent there. or How much time did he spend there.
