As a general rule, if a command does not return an exit status of 0, it means that something failed. I tried out the first four of your scenarios, and ssh returns 255 for the first three error conditions, and returns 2 (file not found) if the remote directory does not exist.
Simply put, check for the return values for the ssh command.

ssh-argv0
SSH-ARGV0(1) BSD General Commands Manual SSH-ARGV0(1)
NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling
SYNOPSIS
hostname | user@hostname [-l login_name] [command]
hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
[-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]
DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is
equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally.
