Careful,
@isekai_yuusha_sama is a hero.
Thank you for picking this up! I wonder why translators keep dropping this series when it's so good.
Hopefully those new reincarnators are not with Nightingale's. Cause the balance of power is already fucked up enough as it is.
As for their identity, I only know abaout Laplace and the one appearing on a japanese shrine is probably Abe no Seimei. No clue on who Maxwell is, or the ones appearing in the hill, samurai in castle, or the one on Pisa tower. The whale is probably Captain Ahab, but since he's fictional maybe Moby Dick's writer Herman Melville. The one on France if were to make a wild guess, Gilles de Rais?
