Answer 1

Simple: validate each question separately using a for-each:

// First, your 'question' input var is already an array, so just get it
$questions = Input::get('questions');

// Define the rules for *each* question
$rules = [
    'fields' => 'required'
];

// Iterate and validate each question
foreach ($questions as $question)
{
    $validator = Validator::make( $question, $rules );

    if ($validator->fails()) return $validator->messages()->all();
}

return 'success';

Laravel Custom Validation for Array Elements

Open the following file

/resources/lang/en/validation.php

Then custom message add

'numericarray'         => 'The :attribute must be numeric array value.',
'requiredarray'        => 'The :attribute must required all element.',

So that, open the another file

/app/Providers/AppServiceProvider.php

Now replace the boot function code by using following code.

public function boot()
{
    // it is for integer type array checking.
    $this->app['validator']->extend('numericarray', function ($attribute, $value, $parameters)
    {
        foreach ($value as $v) {
            if (!is_int($v)) {
                return false;
            }
        }
        return true;
    });

   // it is for integer type element required.
   $this->app['validator']->extend('requiredarray', function ($attribute, $value, $parameters)
    {
        foreach ($value as $v) {
            if(empty($v)){
                return false;
            }
        }
        return true;
    });
}

Now can use requiredarray for array element required. And also use the numericarray for array element integer type checking.

$this->validate($request, [
            'arrayName1' => 'requiredarray',
            'arrayName2' => 'numericarray'
        ]);
