foreach($questions as $num) {
foreach($num as $dano => $v) {

if(gettype($v) == 'array') {
$j = 0;
foreach($v as $val) {
echo '<label>'.$val.'<input type="radio" name="'.$i.'" value="'.$j.'"></label>&nbsp;&nbsp;&nbsp;';
$j++;
}
}
echo '<br>';

if($dano == 'question') {
echo $v . '<br>';
}
}
$i++;
}

И зачем такие сложности?
