I am planning to use google ads only on inside pages(no other ads) and other ads in the home page, so that i could sell my ad banners locally. Is it ok?
Yes, you just can't have two different systems on one site, but lately google changed something in this politics, leaving a way to use some different systems on single site - just search in adsense tips. As far I remember, the ads units has to be visualle distingushable.
If you follow the Adsense Policies on https://www.google.com/adsense/supp...=aso&subid=ww-ww-et-asui&medium=link&hl=en_US which reads Yes, there is nothing stopping you from mixing your ads and Adsense on the same page, you just cannot make your ads look like an Adsense Ad Block so as not to confuse your visitors. If they look vastly different in terms of design then it is fine.
