Docs here show how to specify registration_ids for recipients of multicast messages. Replace your $fields['to'] with a $fields['registration_ids'] which will be an array of strings containing your recipients' tokens.

should it be like this 'to' => [2,3,4,5]

No @Sikander, it should rather be like this: $fields = array( 'registration_ids' => [2,3,4,5], ... );

try this one :

for($i=0;$i<count($TokenArray);$i++){
  send_notification($message, $TokenArray[$i]);
}
