Every book you add to calibre gets a number. This is a database index thingy. You can't change it. If you see the number chances are you are doing something wrong or looking where you are not supposed to look.

Once the books are in calibre you can freely specify and modify published dates and series and series index and much more. You just use the calibre GUI.

Look at the books in the calibre GUI. There you can set and sort on series index and published date and whatever you want to.

Look at the books after you save them to disk. Then you can use a save template to add series info and/or published date to the filenames and/or subfolders.

Look at the books after you sent them to your device. Then you can use a plug board to add info to fields your device use to sort or show the books.

Don't look inside the calibre library. That is rude and demeaning. If you still do it, at least don't admit to it openly. I will say no more about it.
