Captain Rex is not definitively killed off in current Star Wars canon, though he faked his death at the end of the Clone Wars and was presumed dead, later resurfacing as an old man fighting for the Rebellion against the Empire, with his final fate left ambiguous but implied by his presence at the Battle of Endor. He survived Order 66 by having his inhibitor chip removed, but his entire division perished.
I know there are inconsistencies in the Rebel Alliance ranks, but it bugs me Ezra had no insignia but is a Commander, outranking Old Man Rex and Kallus. Hera was also a Captain until towards the end of season 4 when she became a General.
From slaughtering younglings in the Jedi Temple to tracking down survivors across decades, Vader killed dozens of Jedi, both directly and through the Inquisitorius. Canon sources estimate 50–60 Jedi slain, while Legends materials raise the count to over 100, cementing Vader's legacy as the ultimate Jedi executioner.
As far as you know, Anakin Skywalker and Captain Rex were very close friends during the Clone Wars. But before the battle for Coruscant, they had to split up and Rex went with Ahsoka to Mandalore, and Anakin went to Coruscant. After that, Anakin and Rex never saw each other again.

The saddest Star Wars deaths often involve poignant sacrifice, broken relationships, or innocent lives lost, with fan favorites including Kanan Jarrus (heroic sacrifice for his family), Duchess Satine (Obi-Wan's lost love, brutally killed by Maul), Clone Trooper 99 (innocent loyalty and tragic end), Tech (sacrifice for his squad), Padmé Amidala (heartbreak and loss of hope), and Han Solo (fatherly tragedy). These deaths resonate due to their emotional impact, the characters' potential, or the deep impact on other heroes.
He didn't betray Ahsoka by any reasonable measure - he in fact resisted being controlled long enough to tell Ahsoka about Fives, which was enough information to save her and then himself.
No, Darth Plagueis is not Anakin Skywalker's biological father, but there's a strong theory (especially in Star Wars Legends and early drafts) that his experiments with midi-chlorians to create life led the Force itself to create Anakin, the Chosen One, as a reaction, making Plagueis the "unintentional father" of the prophecy. In current canon, Plagueis is a legend Palpatine uses to lure Anakin, and the exact nature of Anakin's conception by the Force remains a mystery, though he had no conventional father.
But when Order 66 was executed, it was Ahsoka who helped to free Rex from the programming of his inhibitor chip. At the dawn of the Empire, Rex has escaped with his life but is considered killed-in-action in the eyes of the new regime.
Baylan defeated Ahsoka in a lightsaber duel, but it doesn't necessarily mean he is more powerful than her. While Baylan is a skilled duelist, he falls short compared to some of the best Jedi duelists like Obi-Wan Kenobi and Mace Windu.
Darth Sidious
We'll start things off with the most powerful Sith in the Star Wars universe. Darth Sidious has been a character in many storylines over the years, most notably in the Old Republic comic books.
The clone commando RC-1136, known as Darman Skirata, got Jedi Knight Etain Tur-Mukan pregnant during the Clone Wars, resulting in their son, Venku Skirata, a Force-sensitive child born outside the Jedi Code's restrictions. Their forbidden relationship and child's birth were detailed in the Republic Commando novels, highlighting the complexities of clone troopers' development and the strictures of the Jedi Order, as Etain was killed shortly after Order 66 while protecting her family.

Lux Bonteri
However, Ahsoka found it annoying, as she immediately shrugged his crush off her. This changed during their time together, as Ahsoka began developing feelings for Lux until she and Padme left Raxus, she and Lux said their goodbyes before going their separate ways.
Darth Vader was probably confused. Last thing Vader saw was Ahsoka being pulled from his lightsaber strike before he fell into the chasm. So he didn't land the killing blow and was probably intrigued by what happened. Even if he did kill her, remorse would unlikely be the emotion to kick in.
It is currently unknown if Ahsoka and Obi-Wan met after Order 66, but Ahsoka became Darth Vader's main target for finding him. After the Battle of Yavin, there's no reason she wouldn't have spoken with Obi-Wan's Force ghost.
Ahsoka Tano from Star Wars: The Clone Wars can also technically be called a Gray Jedi, due to her forsaking the ways of the Jedi, but still following a path of good. However, neither of these two ever trained to use the dark side of the Force, so they are arguably not "true" Gray Jedi.
