Can I use the same AdSense or YAN block code on different pages?

Question

Google Adsense

I have about 100 different ad units in Google AdSense. Each one is pseudo-unique. Those. for example, there is a page for a book, so there are ads block1, block2, block3, block4. And on the book list page: block5, block6, block7.
Question: is it possible to use for example block1 and block2 on the page for example authors? Or is that where you placed it, and should it lie there?
