请翻译成英文

不对。
Thank you,my parents.And thank you, my friends.
Could you tell me the content of your project which you're going to discuss with us?
后面就对了。

many thanks to my family and friends!

could you please tell me the content of the plan that you are going to discuss with us? so i can be prepared beforehand.

第一句不行的，thanks for 是表示 因为...而感谢，for后面就是原因，而且都是跟something 事情，我读四年英语专业了还没见过后面跟人的。
family要改成复数families, 这个单词表示一个整体概念“家庭”的意思时没有单复数之分，如说中国家庭、美国家庭什么的。但当表示“家庭成员，家人”时，有父母，兄弟，姐妹等个人含义时，必须得是复数families ，所以第一句是：
Thank you , my families and my friends.
或者Thanks to my families and my friends.
我个人认为用逗号代替TO比较好。

thank for```就行了``thank you就是[谢谢你]了``
thank for my```thank for all my```

Thank you, my family and friends.
第二句不错
