Are they your pdf files, did you make them? If they are not your files then you won't be able to edit them. Also you will need a pdf editor to do that. To print them is easy. Move your cursor towards the top of the page and find the printer Icon, and click it. It will open your printer properties and you can tell the printer to print just one or a few pages of that files, or all the pages if you so choose. Then click on print. Good luck!
