  Currently you are saving all custom fields as one serialized array, which is better practice.
  You might see how gravity forms handles this and may have input texts in the form to save an array,
  something like
  

  <input type="text" id=data['key'] />

  
  But I don't know if gravity forms supports this.
  
  If you would want to change your metaboxes to save each field as a different key in the db you can use this:
  
  In your code, replace
  

  update_post_meta( $post_id, $key, $data );

  
  
  With this -
  

  foreach ($data as $d => $v)	{
  
  		update_post_meta( $post_id, $d, $v );
  
  	}

  
  
  and also replace your display_meta_box function with this
  

  $data[ $meta_box[ 'name' ] ] = $_POST[ $meta_box[ 'name' ] ];

  
  
  With this -
  
  

  
  
  function display_meta_box() {
  
  	global $post, $meta_boxes, $key;
  
  ?>
  
  	<div class="form-wrap">
  
  <?php
  
  	wp_nonce_field( plugin_basename( __FILE__ ), $key . '_wpnonce', false, true );
  
  	foreach($meta_boxes as $meta_box) {		
  
  		$data = get_post_meta($post->ID, $meta_box['name'], true);
  
  ?>
  
  	<div class="form-field form-required">		
  
  	<label for="<?php echo $meta_box[ 'name' ]; ?>"><?php echo $meta_box[ 'title' ]; ?></label>
  
  <?php if( $meta_box['type'] === 'textarea' ) { ?>
  
  
  
    <textarea name="<?php echo $meta_box[ 'name' ];?>" rows="4"><?php echo htmlspecialchars($data); ?></textarea> 
  
  
  
  <?php } else { ?>
  
  
  
    <input type="text" name="<?php echo $meta_box['name']; ?>"
  
  
  
        value="<?php echo htmlspecialchars($data); ?>" /><?php }?>
  
  
  
  <p><?php echo $meta_box[ 'description' ]; ?></p>
  
  
  
  </div>
  
  
  
  <?php } ?>
  
  
  
  </div>
  
  
  
  <?php
  
  
  
  }

    Thanks Maor this works brilliantly! I presume this could get a bit load heavy for the DB in time depending on the amount of inputs/fields, but will certainly work for now!

  The name of your fields (in the gavity form) are well cf_link, cf_image, and cf_instructions ?
