Each servant requires a different item to make their swimsuits available in the item shop, upon completion you get to unlock a cutscene which will then unlock a new mission to farm items that is required to buy items from the shop and the servant swimsuit materials.

Once you clear all the servants swimsuit section then only will they be unlock in the gacha.

As for the free servant you have to clear the entire shop, all the missions and swimsuits to get him/her.
