Answer 1

Когда утвердительное предложение, пишем some в значении несколько, немного. А any - в значении какой-нибудь, все равно какой. 
В вопросительных и иногда в отрицательных предложениях пишем только any, some там не бывает вообще. Только в отрицательных пишем no, когда самого отрицания в глаголе нет. 

Поэтому:
1. some.
2. any.
3. some.
4. any - some.
5. any - any (хотя во втором случае я бы вообще ничего не поставила).
6. any - some.
