JS file is not loading when i put wp_head() and wp_footer

Something more like this…

function wpdocs_theme_name_scripts() {
    wp_enqueue_style( 'style-name', get_stylesheet_uri() );

    // only enqueue jquery if it is not already enqueued!
    if (!wp_script_is('jquery','enqueued')) {
        wp_enqueue_script( 'jquery', 'https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js', array(), true );
    }

    // note: last parameter only needed here if custom.js actually needs jquery
    wp_enqueue_script( 'script-name1', get_stylesheet_directory_uri() . '/js/custom.js', array('jquery') ); 

    // all other scripts clearly need jquery to run...
    wp_enqueue_script( 'script-name2', get_stylesheet_directory_uri() . '/js/lightbox-plus-jquery.min.js', array('jquery'), true );
    wp_enqueue_script( 'script-name3', get_stylesheet_directory_uri() . '/layout/scripts/jquery.min.js', array('jquery'), true );
    wp_enqueue_script( 'script-name4', get_stylesheet_directory_uri() . '/layout/scripts/jquery.fitvids.min.js', array('jquery'), true );
    // wp_enqueue_script( 'script-name6', get_stylesheet_directory_uri() . '/layout/scripts/tabslet/jquery.tabslet.min.js', array('jquery'), '1.4.2', true );
}
add_action( 'wp_enqueue_scripts', 'wpdocs_theme_name_scripts' );

EDIT: to add this one separately in footer…

add_action('wp_footer','tabslet_script');
function tabslet_script() {
    echo '<script src="'.get_stylesheeet_directory_uri().'/layout/scripts/tabslet/jquery.tabslet.min.js"></script>';
}
