I want to use Amazon affiliate program on my website, but my site have adsense ad. Will it be any problem to use Amazon besides Adsense ?
You can use Amazon or other affiliate links in your site but make sure that any other ads cannot be confused with Adsense. No worry here. Amazon ads are pretty distinctive.
why would you not use multiple affiliate and adsense programs - as long as you don't clutter your pages with ads, there would be no issue
