Answer 1

This code will create order with custom price:

$product = wc_get_product($product_id);
$order = wc_create_order();
try {
    $order->add_product($product);
    //$order->set_customer_id($user->ID);
    $order->set_billing_email($customer_email);
} catch (WC_Data_Exception $e) {
    wp_send_json_error("Failed to create order");
}

$order->calculate_totals();    

try {
    $order->set_total($custom_price); // $custom_price should be float value
} catch (WC_Data_Exception $e) {
    wp_send_json_error("Failed to change order details");
}

$order->save();

$order->update_status( 'completed' );
