"Each" is a very specific type of condition which allows applying the discount only when Each of the combinations of the specified products is available in the cart.
It is more like a bundle product discount.
The discount will be applied only when each of the mentioned are purchased.
Here we have come up with an example like, Buy each Cap + Belt + Sunglasses to get the discount on all those products.
Let's see on how to set such a rule:
Navigate to Woocommerce --> Woo Discount Rules --> "Add new rule".
Since I am applying the discount on product prices, I am choosing the discount type as Product Adjustment.
The discounts will be applied in the cart when each of the mentioned products is added to the cart.
Instead of choosing percentage discount, you can choose fixed discount/fixed price in the discount section.
