Prototype 35.6cm is generally for support expeditions with Kongo, Fuso and Ise classes. I don't really think you need more than 1 of these, as 35.6cm +9★ is better for sortie use.

38cm Kai is... well, expensive. You can get 5 of them from a single Bismarck, but resources from screws and blueprints will take a beating.

I think you should start off with 4x 35.6cm +4~9★, and 4x 41cm +4~9★, as this offers quite a lot of flexibility. If, for some reason, the map requires something like All Kongo sisters, you can substitute in prototype and dazzle guns, but I found such maps to be rare.

You should also improve those Type91 AP shells to +9★ after finishing your guns.
