Just finished Tokyo ghoul 😔i have some questions

Hey guys I just finished Tokyo Ghoul (fuckin masterpiece) and I have some questions that I need answered if possible:
1) Did Akira & Amon officially get together
2) What happened with Nishiki & Kimi (are they also together again?)
3) Where did Takizawa go and what happened to him
4) Is Eto Yoshimura dead?
