                        <input type="text" name="question" class="question"  value="<?php echo $print->question ?>" ></td>
                     <td>
                     <input type="text" name="answer" class="answer"  value="<?php echo $print->answer ?>" > </td>

                     <td>
                        <input type="button" value="Insert" id="insert" data-id = "<?php echo $print->id ?>" name="insert" class="ins_btn">
                    </td>

                    <td>
                        <input type="button" value="Update" id="update" data-id = "<?php echo $print->id ?>" name="update" class="upd_btn">
                    </td>

                     <td>
                        <input type="button" value="Delete" id="delete" data-id = "<?php echo $print->id ?>" name="delete" class="del_btn">
                    </td>
                </tr>

jQuery('.ins_btn').click(function(){
        var id = jQuery(this).attr('data-id');
        var question = jQuery('#question').val();
        var answer = jQuery('#answer').val();
        // alert(id);
        $.ajax({
            url: '<?php echo admin_url('admin-ajax.php');?>', 
            type: 'POST',
            data:{ 
              action: 'insert_records', 
              insert_record : id,
              insert_question: question,
              insert_answer: answer
            },
            success: function( data ){
                alert("Records are successfully insert");
                location.reload();
            }
         });
    });

insert query

 function insert_records(){
  global $wpdb;
 $id = $_POST['insert_record'];
 $question = $_POST['insert_question'];
 $answer = $_POST['insert_answer'];


  $db_inserted = $wpdb->insert( $wpdb->prefix.'faqq', 
        array( 'ID' => $id, 
               'question' => $question, 
               'answer' => $answer) 
    );
}
add_action( "wp_ajax_insert_records", "insert_records" );
add_action( "wp_ajax_nopriv_insert_records", "insert_records" );

ajax for update the data

jQuery('.upd_btn').click(function(){
        var id = jQuery(this).attr('data-id');
        var question = jQuery('#question').val();
        var answer = jQuery('#answer').val();
        alert(question);
        $.ajax({
            url: '<?php echo admin_url('admin-ajax.php');?>', 
            type: 'POST',
            data:{ 
              action: 'update_records', 
              update_record : id,
              update_question : question,
              update_answer : answer

            },
            success: function( data ){
                alert("Records are successfully updated");
                location.reload();
            }
         });
    });

update query

function update_records(){
  global $wpdb;
  // $table_name = $wpdb->prefix.'faqq';
  $id = $_POST['update_record'];
  $question = $_POST['update_question'];
  $answer = $_POST['update_answer'];
  $db_updated = $wpdb->update( $wpdb->prefix.'faqq', 
        array('question'    => $question,
              'answer'   => $answer, array( 'ID' => $id ) )
          ); 
}

Here are some errors. 1)Getting error when update the data through ajax- https://prnt.sc/wnymkx, https://prnt.sc/wnyos5, https://prnt.sc/wnyuhk

Answer

Don’t need id field for inserting data, So I remove it. I use classes for question and answer fields.

jQuery('.ins_btn').click(function(){
        var question = jQuery(this).closest('tr').find('.question').val();
        var answer = jQuery(this).closest('tr').find('.answer').val();
        // alert(question);
        $.ajax({
            url: '<?php echo admin_url('admin-ajax.php');?>',  
            type: 'POST',
            data:{ 
              action          : 'insert_records', 
              insert_question : question,
              insert_answer   : answer
            },
            success: function( data ){
                location.reload();
            }
         });
    });

Same as for update function, only add reference id field. Because for updating the data, reference Id is important.

jQuery('.upd_btn').click(function(){
        var id = jQuery(this).attr('data-id');
        var question = jQuery(this).closest('tr').find('.question').val();
        var answer = jQuery(this).closest('tr').find('.answer').val();
        
        $.ajax({
            url: '<?php echo admin_url('admin-ajax.php');?>', 
            type: 'POST',
            data:{ 
              action: 'update_records', 
              update_record : id,
              update_question : question,
              update_answer : answer

            },
            success: function( data ){
                location.reload();
            }
         });
    });

And in update query, I added parenthesis at wrong position.

function update_records(){
  global $wpdb;
   // echo "<pre>"; print_r($_POST);
   // die();    
  // $table_name = $wpdb->prefix.'faqq';
  $id = $_POST['update_record'];
  $question = $_POST['update_question'];
  $answer = $_POST['update_answer'];

  $db_updated = $wpdb->update( $wpdb->prefix.'faqq', 
        array('question'    => $question,
              'answer'   => $answer
          ),
               array( 'ID' => $id ) 
          );

  // $wpdb->query($wpdb->prepare("UPDATE $table_name SET question = '$question', answer = '$answer' WHERE id = $id"));
}
add_action( "wp_ajax_update_records", "update_records" );   //update_records is action
add_action( "wp_ajax_nopriv_update_records", "update_records" );
