Asalamelekum Hazarat,
الجواب وبالله التوفيق
Your question has three parts. In the last part is the narration of the past event, therefore, there is no need of response for that part.
In the first part is the mentioning of yourself and your uncle hearing the three Talaq but with the explanation of the husband those relate to the future, therefore, it will come under the category of the promise of Talaq which will not result in any divorce taking effect.
In the second part there is only mentioning of the discussion about Talaq. If at time either, the husband actually didn’t give any Talaq then no divorce took effect.
However, if there is any other situation then write in the details as occurred for response.
قال الزوج أطلق۔ طلاق می کنم فکررہ ثلاثاً طلقت ثلاثاً بخلاف قولہ سأطلق طلاق کنم لانہ استقبال فلم یکن تحقیقاً بالتشکیک
(عالمگیری کتاب الطلاق۔ فصل سابع)
واللہ اعلم بالصواب
