I think Makima will resurrect because she has a contract that allows that, or she is like Denji and knife-devil-fusion and can regenerate.

Pretty sure Eyepatch is dead. She had 3 episodes of development but isn't with the gang in the OP animation. Same logic with Makima. She is too present in the OP to be dead without any demystification of her character.

Someone needs to pull Denji's chain...
