Well, it means what it says... There's no file named '2'. If you want to give it some other, more valid filename, you are free to do so.
It takes the & to mean 'run this command in background and take the text after as a new command'.

I would like to substitute file file with some that returns file two or more in on go.
I do not understand this. If you want awk to read the file twice, you tell it the file twice; that's how it works. But I don't think your question is crossing the language barrier very well.
