Answer 1

Is it possible to get information on a branch on a remote server without fetch?

Limited. See git ls-remote .
You can find the hash:

$ git ls-remote origin refs/heads/master
2595646791c319cadfdbf271563aac97d0843dc7        refs/heads/master

Answer 2

No way. Through fetch, you deliver the state of the remote repository to yourself. Then you can combine this state with your local state or not.
