I found the solution thanks to the link above.
Is someone may interest in it, I post the right code below

// I register all my script in 1 function first
function organizedthemes_load_default_scripts() {
    if( !is_admin()){
wp_register_script( 'booking_language_it', get_template_directory_uri() . '/globalize/globalize-it.js', array( 'jquery' ), null , true);
wp_register_script( 'booking_searchbox_it',  'https://be.bookingexpert.it/book/websites/searchbox?hotel=5098&lang=it', array (), null , true);
wp_register_script( 'booking_modulo', get_template_directory_uri() . '/globalize/searchbox.js', array (), null , true );
wp_register_script( 'booking_language_en', get_template_directory_uri() . '/globalize/globalize-en.js', array( 'jquery' ), null , true);
wp_register_script( 'booking_searchbox_en',  'https://be.bookingexpert.it/book/websites/searchbox?hotel=5098&lang=en', array (), null , true);
		 }
}
add_action('wp_enqueue_scripts', 'organizedthemes_load_default_scripts');

// function with  coditions
function be_script_it() {

// if the page is called/ with slug 'home' the load xx script
if(is_page( 'home' ) ){
wp_enqueue_script('booking_language_it');
wp_enqueue_script('booking_searchbox_it');
wp_enqueue_script('booking_modulo');
}
// if is not true then load yy script
else{
wp_enqueue_script('booking_language_en');
wp_enqueue_script('booking_searchbox_en');
wp_enqueue_script('booking_modulo');
}
}
add_action('wp_enqueue_scripts', 'be_script_it');

As is now the code load the second part of the script in all pages except for ‘home’. In my case I need the scripts in just 2 pages (en+it) and 4 post (en+it), so I changed the second part of my function like this

function be_script_it() {
// if is this specific IT page title and this IT posts title then load IT script
if(is_page( 'home' )|| is_single( array( 'camera-deluxe', 'camera-classica' ) )  ){
wp_enqueue_script('booking_language_it');
wp_enqueue_script('booking_searchbox_it');
wp_enqueue_script('booking_modulo');
}
// if is this specific EN page title and this EN posts title then load EN script
if(is_page( 'homepage' )|| is_single( array( 'deluxe-room', 'classic-room' ) )  ){
wp_enqueue_script('booking_language_en');
wp_enqueue_script('booking_searchbox_en');
wp_enqueue_script('booking_modulo');
}

// if both cases aren't true then load nothing
else{}
}
add_action('wp_enqueue_scripts', 'be_script_it');
