  is it possible to combine this command?

  %grep ^. *list | grep -v @

      What does '+$' do??

Uh, it is "[^@ ]+", which matches one or more non-blank, non-"@" characters.
And, sorry, but I should have written "egrep", not "grep".  "Egrep" supports
the "extended" regular expressions, including "+".

The trailing "$" is the "end of line" marker.

If you don't have "egrep", the equivalent grep expression is:

    grep '^[^@ ][^@ ]*$' *list
