Some website has already adsense. Is it allowed to place adsense from different account? I want to remove adsense ads (account A) and place adsense ads from (account B). Do you think is this fine? allowed?

Of course you can switch out the adsense ads, I believe you could even have adsense ads from two different accounts on the same website. Digitalpoint does it everyday with their ad-sharing system.
Yes, you can do this without any problem, i also did this two months ago due to some reason, i used account of my brother for one month and again i started using mine, without any problem.
