Does the following sentence
It is not good for all men here.
mean
1) It is not good for anyone here.
or
2) It is good for some of them, while not good for others.
I know I can use
It is not good for any man here
to precisely express the first meaning. But what's the meaning for the original sentence exactly ? Does it matter if it changes a bit like
It is not even good for all men here.
