General setup question

SO when i am adding meta boxes in my function file do i need to add a function everytime i add a prefix? or do i just change the prefix to something like $prefix_two? Or am i doing it completely wrong. Here is my code for my home page meta boxes.

/* ********* adding custom metaboxes ***************** */
add_action( 'cmb2_admin_init', 'home_custom_metaboxes' );
/**
 * Define the metabox and field configurations.
 */
function home_custom_metaboxes() {

	// Start with an underscore to hide fields from custom fields list
	$prefix = '_section_one_content';

	/**
	 * Initiate the metabox
	 */
	$cmb = new_cmb2_box( array(
		'id'            => 'section_one_content',
		'title'         => __( 'Section One Content', 'cmb2' ),
		'object_types'  => array( 'page', ), // Post type
		'context'       => 'normal',
		'priority'      => 'high',
		'show_names'    => true, // Show field names on the left
		'cmb_styles'    => true, // false to disable the CMB stylesheet
		'closed'        => false, // Keep the metabox closed by default
		'show_on'      => array( 'id' => array( 2, ) ), // Specific post IDs to display this metabox
	) );

	// main section headline
	$cmb->add_field( array(
		'name'       => __( 'Headline', 'cmb2' ),
		'desc'       => __( 'add a headline for the about section', 'cmb2' ),
		'id'         => $prefix . '_text',
		'type'       => 'text'
	) );

	// headline for first about section
	$cmb->add_field( array(

i basically want a new meta box for each section so they can be opened and closed so i guess i just need to know if the code is set up right or if i am doing something wrong. Everything is working, I don’t want ot have any conflicts later on down the road. thanks for any help
