Ako and Ayako, good job! The first dialogue was done naturally since you did it in front of the vending machine! (自販機の事をこういいます）It would be better to say, lend me, instead of give me when you want to borrow money. The second scenario, the reason to borrow money was given before you asked a favour, which is good! You might want to let the interlocutor (対話者の事をこういいます）to offer first without asking for the favour yourself. But all in all, your dialogues were well thought out and I liked both of them! :)
