Проверте вопросы, пожалуйста

[Donkibot]

Я английский достаточно неплохо понимаю, но разговаривать и , тем более, составлять вопросы у меня вообще не получается. Я сам составил все эти 15 вопросов, но ,скорее всего, все они неправильно построены.
Если не в тягость, подкорректируйте, пожалуйста, вопросы.
