Nah! An individual is allowed to have only one account. But, he can get another one on business name.
Is it written anywhere in their TOS because I have never heard that you cannot have more than one Google account!
This is from the FAQ on Google. Of course if your are talking about Adsense the answer is: https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=9729
I don't see why you can't, use an ip changer to setup the account so it looks like its from a different computer. I don't see why you can't though, just don't tell them.
Yep! Here is your more in depth(not the specific question answered, but shows you can have multiple accounts ) http://help.blogger.com/bin/answer.py?hl=en-nz&answer=42532
