How to display field on the page?

Add the_field($field_key, $post_id) or get_field($field_key, $post_id) into page
template where it is necessary for you (use $field_name only, if you are sure that field value exists):

<?php
    // add fields in the Loop
    if ( have_posts() ) {
        while ( have_posts() ) {
            the_post();
            if ( function_exists( 'the_field' ) ) {
                the_field( 'quality', $post->ID );
            }
            the_content(); 
        } // end while
    } // end if
?>
<?php
    // display rating field for post_id=123
    if ( function_exists( 'the_field' ) ) {
        the_field( 'interest', '123' );
        the_field( 'field_62ad11se531h', '123' );
    }
?>
<?php
    // display rating field of user_id = 1
    // to pass $post_id value use 'user_' + user ID format
    if ( function_exists( 'get_field' ) ) {
        $field = get_field( 'field_53ac25b2e521', 'user_1' );
        echo $field;
    }
?>
