What do you mean by together? On the same page? Within the same column? FYI, the max ad units allowed on one single page is 3.
Distribute your ad block to different places so the ads are available on every section of page.If you put all the ads together then it might throw massage to your visitor that your interested in showing ads only.People come to our site for information,if the information is useful they will stay for long time and search for details about the subject by clicking on the ads.
by the way its not v its we and its ad not add also i don't suggest you put your ads back to back close to each other either
I think that will be ok, but that can result in a page or site which will look like a MFA site. I also suggest that you should ask adsense support if doing such thing is ok.
In my opinion doing that would make your site look like it was a MFA site (which it may well be anyway, but it's best not to push your luck).
