Answer 1

By setting the $css value and changing it every 5 records:

@php $count = 1; $css = 'honeydew'; @endphp
                            @for($i = 0; $i <= 99; $i++)
                                @php
                                    if($count % 6 == 0){
                                        $css = ($css === 'honeydew' ) ? 'aliceblue' : 'honeydew';
                                    }
                                    
                                $count++;
                                @endphp
                                <tr class="allrow {{$css}}" id="row_{{$i}}">
                                    <td width="20%">
                                    <select class="form-control select2 firstname v1" id="name1_{{$i}}" name="name[]" style="width: 100%;">
                                        
                                    </select></td>
                                    <td width="20%"><input type="number" name="winlose[]" id="amt1_{{$i}}" class="form-control first" value="0.00"></td>
                                    {{-- <td width="20%"><select class="form-control select2 secondname v1" id="name2_{{$key}}" name="name2[]"></select></td>
                                    <td width="20%"><input type="number" name="winlose[]" id="amt2_{{$key}}" class="form-control second"></td> --}}
                                    <td width="20%"><a href="#" class="btn btn-danger remove">-</a></td>
                                </tr>
                            @endfor

Answer 2

Here's a basic example in PHP using regex. Basically, it will check if the number ends with 0-4 and set CSS to honeydew, if not set to aliceblue.

for ($i = 0; $i <= 99; $i++) {

    if (preg_match('/[0-4]$/', $i)) {
        $css = 'honeydew';
    } else {
        $css = 'aliceblue';
    }
    echo $css . PHP_EOL;
}
