Are all those in the same remote file?, if so its only doing the first one, then it stops as it only well do one identical event in a remote file. (this might be wrong as the levels are 1 1 *, which might make the event unidentical? i dont know i always use *)
you could try this, if there all in one file.
on *:NOTICE:*:*: {
if ($nick == sexgod) sx2echo 14,0 $+ $sx2.kbig( $nick ) $sx2.sgod( $1- )
if ($nick == nickserv) sx2echo 14,0 $+ $sx2.nksv( $nick ) $sx2.nksv( $1- )
if ($nick == memoserv) sx2echo 14,0 $+ $sx2.cham( $nick ) $sx2.cham( $1- )
}
