问一句简单的英语~谢谢帮忙。

"Ok, I'll tell you when I have time. I miss you,too."

ok ,I will tell you if I have time,and hope to meet you,too

Well,I'll tell you as soon as I'm f ree.I want to see you very much too.

Yes, if I have time to tell you immediately.
I also want to see you

"All right ,I will tell you immediately if I have time. I also want to see you."

从中文的语义上推断，提问人好像在电话里接到一个邀请，参加个什么活动，或者与对方见个面，但是因为没有空而推辞了。但是对方却一再坚持，提问人只好说“我有时间（参加或见你）的话会马上告诉你的”，因此可以这么说

Yes, I'll let you know as soon as I get time (to go/to come/to see you/to dinner with you...).或者

Alright, I'll tell you as soon as possible (right away) when if I am free (available/get time...).

“我也很想见你。”如果是情人之间，或者是密友，可以说“I miss you (too)”，既亲切又自然。如果不是以上两者之间的话，还是说“I'd like to see/meet you too”。
