First of all, your script will fail to work because of an extra, redundant *: symbol to your input event. I've tried to improve your original script by modifying it to this:

on @*:INPUT:#: {
  if (/* !iswm $1-) {
    if ($1 == k) && ($2 ison #) { 
      raw -q kick # $2 4BReaking Rules 
    }
    if ($1 == b) && ($2 ison #) { 
      ban -ku180 # $address($2,2) 43 minute ban 
    }
    if ($1 == akick) && ($2 ison #) { 
      ban -k # $address($2,2)
      guser akick $address($2,2) 
    }
  }
}
on @akick:JOIN:#: {
  set -e %nick $nick
  set -e %chan #
  .timeryn 1 0 yesno 
}
alias -l yesno { 
  $iif($input(Do you Wanna akick %nick $+ ? Yes or No?,yv) != $yes,guser unakick %ban,ban -k %chan %nick 2) 
}
