帮我看看我这句英文写得对吗？谢谢

Mr Lee is your friend,and he wants you call back to him if you are free。

改
Mr Lee is your friend, would you call him back if you are free?

或者可能是
Mr Lee is your friend, he would call you back if you are free.
后半句全乱了...不知什么意思

不对
如果你的意思是"如果你有时间他会叫你回来"
那么应该是
He would call you back if you are free

Mr Lee is your friend, he would like you call him back if you are free.

Mr Lee is your friend,He wanna you call him back if you are free .

Mr Lee is your friend.He wanted you call him back if you free.
