If you have an identifier in your table question, you could use it.
But you could just use a variable to increment question number :
$index = 1 ;
while($row = $result->fetch_assoc()) {
echo "<br>";
echo "Q:" . $row["question_name"]. "<br>";
echo "<input type='radio' name='question".$index."' value='answer1.1'/ >
<code>".$row["answer1"]."</code>". "<br>";
//...
$index++;
}
