1.) In checkout page we have flat rate for shipping 5€ and for Saturday 8€ (we want flat rate as standard 5€ and give the option of 3€ to add for Saturday but total we want count as 8€) the question is it possible?
2.) We want to add the option to the checkout for an invoice (to fill in the customer’s details vat, company details etc…) do have any plugin suggestions?

1) We never face such shipping rules by date, so, I don’t have recommended plugins for you. Contact WooCommerce plugin support on support forum because it’s related to WC default option. Maybe they will find the solution for you.
2) You can use WooCommerce EU VAT Number plugin if you need to add VAT field at the checkout. You can try WooCommerce PDF Invoices plugin to generate invoices.
