When using a Document / PdfWriter pair to create a document, you create the pages in their final order, i.e. you first create the first page, then the second, then the third, ...

In your code you appear to try to start by creating the third page and then continue by creating the second one. You'll have to sort the code accordingly.

As soon as you have sorted your code, you can use the Document method NewPage to switch to the next page:

document.NewPage();

Beware, though, iText ignores the NewPage call if there is no content whatsoever on the page in question. To override this, you can make iText believe it is not empty using the PdfWriter property PageEmpty before calling NewPage:

writer.PageEmpty = false;
document.NewPage();

That been said, though...

For such a task you should not use a Document / PdfWriter pair to start with, use a PdfReader / PdfStamper pair! In a PdfStamper you can quite freely jump between pages...
