Answer 1

Change your form:
...
<td><input type="checkbox" name="row[{{$key}}][data]" value="0;{!! $activity->ActivityId !!};{!! $activity->Rate !!};0;0;{!! $activity->ActivityName !!}" />
</td>
<td>{!! $activity->ActivityName !!}</td>
<td>{!! $activity->Rate !!}</td>
<td>{!! Form::text('row[{{$key}}][txtnos]','',['class' => 'form-control small-textbox ','txtnoid'=>$activity->ActivityId]) !!}</td>
...
So the only thing that's changed is the name of data and txtnos, it will give you the following:
$exampleResult = [
'row' => [
// old $key as new key
0 => [
'txtnos' => 'entered value',
'data' => '1', // But only if checked
],
1 => [
'txtnos' => 'entered value',
'data' => '1', // But only if checked
],
]
];
Validation rules
$rules = [
'row.*.txtnos' => 'required_with:row.*.data'
];
In the example, txtnos on each row is required if data on the same row isset.
Validation message
$messages = [
'row.*.txtnos.required_with' => 'Enter a value or uncheck the checkbox..'
];
Important:
The validation for .*. was added in Laravel 5.2, you didn't specify your exact version so I'm not sure if it will work for you. Anyway, there is another way to do this.
For versions < 5.2, loop the input rows and replace the * in my example with the current key.
