Краткий ответ:

1. I was doing my homework when the lights suddenly went out.

3. He fell asleep while he was watching a film.
4. We were waiting for the bus at 7 p.m. yesterday.
5. She finished her project, printed the pages, and put them in her folder.

Как выбрать время:

• Past Continuous: was/were + глагол-ing — действие уже продолжалось в определённый момент прошлого.
  Например: was doing, were having, was watching, were waiting.
• Past Simple — короткое завершённое действие или последовательность событий.
  Например: went, arrived, fell, finished, printed, put.

В предложениях 1–3 длительное действие прерывается или сопровождается коротким событием:

• was doing → went out;
• were having → arrived;
• was watching → fell asleep.

В предложении 5 действия идут одно за другим, поэтому используется Past Simple. У глагола put форма в прошлом не изменяется: put — put — put.
