    ('".implode("','",$fin_element)."')";

    $result = $conn->query($sql);

    if ($result->num_rows > 0) {
   // output data of each row

   while($row = $result->fetch_assoc()) {
     echo "<br>";
     echo "Q:" . $row["question_name"]. "<br>";

    echo "<input type='radio' name='question1' value='answer1.1'/    >
          <code>".$row["answer1"]."</code>". "<br>";

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++;
 }
