From man sh

-c string   If the -c option is present, then commands are read from string. 
            If there are arguments after the string, they are assigned to the
            positional parameters, starting with $0

It means your command should be like this:

 $ sh -c 'echo $0' foo 
 foo

Similarly:

$ sh -c 'echo $0 $1' foo bar
foo bar

That was the first part to understand , the second case is simple and don't need explanation  , i guess.
