I use the following:
http://code.google.com/p/lh-vim/source/browse/misc/trunk/vimrc_core.vim#516

If the len of the current buffer is null, and that there only one empty line, then I consider I'm sitting at this [No Name] buffer.
It also works after a :new.

HTH,

PS: you can also play with:
:echo len(filter(map(lh#buffer#list(), 'bufwinnr(v:val)'), 'v:val != -1'))
to obtain the list of opened windows and their number. But regarding what you are looking for, this is a very complex solution.
[lh#buffer#list() comes from lh-vim-lib, see my signature)
