Complicated promotions with discounts and gifts

I own a pizzeria and I want to apply the following types of campaigns:

1. Order 5 “huge” size pizzas and receive 1 “huge” size pizza as a gift
2. Order 4 “large” size pizzas and receive 1 “large” size pizza as a gift
3. Order 2 “large” size pizzas and receive 1 “small” size pizza as a gift

Basically, we have promotions based on attributes, pizza sizes: huge, large, small.

The problem is with promotion number 2 and 3, because i have the promotions on the same attribute “LARGE” and when i put 2 large pizza in the cart, i receive 1 small pizza but when i put 4 large pizza in the cart i only want to receive 1 large pizza.

We also want to apply a coupon called TOP10, and when it is applied to the cart, the customer will receive a -15% discount, but only on the types of pizza that are not part of the promotions above.

Basically, if I add the promotion to the cart -> Order 2 “large” size pizzas, you get 1 “small” size pizza as a gift. In addition to this promotion, I also add 1 small pizza to the cart, the discount coupon should be applied to the small pizza, not to all the products in the cart.

Is it possible to implement such complicated promotions?
