¿se puede publicar en Publish Online desde un Libro de Indesign?

How many Chapters, pages per Chaptter?

You could make a copy of the first chapter, then duplicate all pages from other chapters.

I don't think you can. 

But what I've done in the past is to create a PDF of the book 

Then use this script https://creativepro.com/zanelli-releases-multipageimporter-for-importing-both-pdf-and-indd-files/https://community.adobe.com/t5/indesign-discussions/place-a-multipage-pdf-in-indesign/td-p/11343293

Once it's in a single document as a PDF or InDesign files are placed into a single document - you can then export to Publish Online.

I prefer just placing the InDesign file - and if something happens in your source (original) documents - then open up the new document where you have placed all your pages in a single document, you only need to update the Links - then publish online again.
