你很可能就是我想要约会的女孩。 他就是我想要和他说话的那个人。 那个就是我想要给礼物的那个老师。

To tell you the truth is quite simple. You can see it like this. 你是我喜欢的类型，可以约你吗？I hope it can help.

你可能是我想约会的那种女孩。 Why you say He is the man that I wanted to talk to, you don't say he is the man I want to talk to, that's really different in Chinese. Either does the last sentences.

No problem. I took no offense. :)

You might be the kind of girl that I'd like to date. 你是我想约会的类型。 He is the man that I wanted to talk to. 他是那种我想跟他说话的男人。Chinese say “我想跟他说话” directly. That is the teacher that I wanted to give a present to 我想送一份礼物给这个老师。（I wanted to give a present to the teacher.）
