I'd like to have a free conversation please. We have 10 mins left for this lesson.
Can we have a free conversation for the rest of the time?
Could we please use the remaining lesson time in free talk?
Explanation:
1. I'd like to... = clearly shows what you prefer doing.
2. While "Could you please..." is more polite, 'can you please....' is also used. There are different levels of politeness, respect or courtesy inmost languages. Depending on the situation, most native speakers will use 'can you please....' or 'could you please...' in their conversations.
3. To express 'rest of the time' we can say 'for the 10 mins left', 'the remaining time', 'the balance time', etc.
説明:
1. I'd like to... = （～したいです）あなたがしたいことを明確に示すことができます。
2. "Could you please..."（～して頂けますか）というほうが丁寧ですが、'can you please....' （～してくれますか）というのも使われます。ほとんどの言語で、丁寧さや、敬う心、礼儀を表現するには様々な度合いがありますよね。状況に応じて、ネイティブスピーカーは、'can you please....' と 'could you please...'を会話で使い分けます。
3. 「余った時間」を表現するには、'for the 10 mins left'（残り10分）、 'the remaining time'（残りの時間）、 'the balance time'（残りの時間）と言うこともできます。

As we've completed the material, could we have a free conversation now?
If you have completed the material that has been the focus of your lesson, then it is both friendly and educational to have a free conversation towards the end of the allocated leson time. Your teacher may well slip into a conversational mode if the material has been completed, but if not, then you may easily ,ead the proceedings toward conversation by suggesting:
"May we please do free conversation now?"
あなたがレッスンの焦点としていた教材を終了したのなら、残りのレッスン時間をフリートークに割り当てることは、勉強の一環としてとても良いと思います。
その日やるべき教材が終了した場合、講師のほうで自然にフリートークに移行することもありますが、
そうでなかった場合、以下のようなフレーズを言ってみると良いでしょう：
"May we please do free conversation now?"
Let's just have a free conversation with the rest of the time.

B. Yeah, I agree, it would be better to stay at home and rest and recuperate for one day.
