1. No, Kiri was already known as the Bloody Mist before Obito became Tobi and mind controlled Yagura. We do not know the duration of Yagura's reign though. Chapter 605 reveals this.

2. It could simply be confidential information that was privy only to the higher ups of Kiri similar to info about Naruto being a jinchuriki in Konoha. After all, this is some serious stuff that could implicate the village's structure and could cause some trouble if the common villagers knew their leader was being manipulated.

3. Yagura says in chapter 572 that he is an adult, simply just a very young looking adult that is. Boruto also thought Shizuma was a lot older than he looked.

4. Ever hear of this thing called a clan or a family? Just bc they have the same last name doesn't mean they're father and son. That's like saying Asuma is Konohamaru's father just bc they're both from the Sarutobi clan.

5. Not really, Samehada is a sword that belongs to the Hidden Mist village so B must've returned it to them. I'm pretty sure Shizuma got that sword since he's from the same clan as Kisame, just because the studio probably felt like making that connection.

I think you're probably just thinking too much about this, or perhaps not enough.
