Your brace brackets are incorrectly aligned.

Fixing those, and condensing your code by combining statements brings up this
Code:
 alias aura {
  if ($readini(wars.ini,$nick,aura) = beginner's) || ($v1 == Luigi's) {
    return $nick $+ $auratwo($readini(wars.ini,$nick,char))
  }
}
alias aura2 {
  if ($readini(wars.ini,$1,aura) = beginner's) || ($v1 == Luigi's) {
    return $1 $+ $auratwo2($readini(wars.ini,$1,char))
  }
}
alias auratwo2 {
  if ($readini(wars.ini,$nick,aura) = beginner's) || ($v1 == Luigi's) {
    return 04(00 $+ $1- $+ 04)00
  }
}
alias auratwo {
  if ($readini(wars.ini,$nick,aura) = beginner's) {
    return 04(00 $+ $1- $+ 04)00
  }
  elseif ($v1 = Luigi's) {
    return 09(3 $+ $1- $+ 09)00
  }
}


As I don't have the proper INI file, I can't test this properly, but it should work for you.
