Вот как я бы заполнил эти предложения, используя will / won't / shall + глагол:

1. A: I can't open this window.
   B: I will help.

2. A: It's a secret.
   B: Shall I tell you?

3. A: When will I see you again?
   B: I will call you tonight.

4. A: Can I borrow €50?
   B: I will pay you back tomorrow.

5. A: It's my birthday next week.
   B: Don't worry. I won't forget.

6. A: I don't feel very well.
   B: Shall I take you home?

Здесь я постарался использовать естественные варианты будущего времени: "will" для обычного обещания или действия, "won't" для отрицания, и "shall" в вопросительной форме для предложения помощи или совета.
