这用英文怎么说，急

给你相当口语的回答，这边的美国人都这么讲：
are you here?
all right, I'm coming down

看情形是男友已经到楼下了，
所以，这个翻译应该是，
are you here?
okay, I'm coming down.

Are you here (already)?

Okay. I'm coming down (right away).
或者说 I'm on my way down.

1.Have you arrived?
2.Ok.I am down right away.

1.Have you arrived?

2.OK, I will be there right now.

绝对对的~~~

Are you there?
OK, I will be there in a minute.
