Answer 1

Not that I know of:
Git is not a server, there is nothing by default listening to a request (unless you activate a gitweb, or a gitolite layer)
And the command "git remote ..." deals with the local copy (fetched) of a remote repo.

So unless you fetch something, or clone --bare a remote repo (which does not checkout the files, so you only have the Git database alone), you won't have an idea of its size.
And that does not include the size of the working directory, once checked out.
