For the select you will not need to do array in the name and you don't need to add name to the options as well :
<select id="custom-select" class="form-control custom-select" name="id_s" >
<option disabled="true" selected="true" value="choose">choose</option>
#foreach($subject as $s)
<option value="{{$s->ID}}" >{{$s->NAME}} / {{$s->CREDIT}}</option>
#endforeach
</select>
and the validation like this :
'id_s' => 'required|not_in:choose'
