Despite having left the Jedi Order for some time prior, Skywalker's former Padawan, Ahsoka Tano, was targeted by Order 66, as was the former Sith Lord Maul.
The closest to an actual number we ever get is from Kanan Jarrus in the Rebels episode “Path of the Jedi”. He says to his Padawan, Ezra, “When I was your age, there were around 10,000 Jedi Knights defending the galaxy.” That would have been during the Clone Wars, just before Order 66 was issued.
The first Padawan to Jedi Knight Qui-Gon Jinn, Feemor was successfully trained to Knighthood by Jinn, who was in turn granted the title of Jedi Master. Jinn later took a young boy named Xanatos as his second student, but the latter turned against his Master.
The Padawan of Depa Billaba, Caleb Dume survived Order 66 thanks to Clone Force 99. As seen in Star Wars: The Bad Batch season 1, these mutant clones could resist their inhibitor chips, and they were understandably bewildered when their brother clones started executing Jedi.
The very first Jedi in Star Wars canon is a nameless figure known as the Prime Jedi. He was likely the builder of the first Jedi Temple on Ahch-To, seen in The Last Jedi.
However, some of the most powerful and ruthless Jedi Masters in the Star Wars universe include Mace Windu, Yoda, Obi-Wan Kenobi, Qui-Gon Jinn, Luke Skywalker, and Anakin Skywalker (prior to his turn to the dark side).
Legend had it that Yoda—a Jedi who became Grand Master—was trained by N'Kata Del Gormo. A Force-sensitive Hysalrian, N'Kata Del Gormo was trained in the ways of the Force and achieved the rank of Master within the Jedi Order.
Yes, a few Younglings are known to have survived Order 66, including an unnamed Rodian seen in Jedi: Fallen Order. The most famous Youngling survivor is “The Child,” Grogu.
Nearly all the surviving Jedi Knights were hunted down and killed by Darth Vader, while Order 66 remained in effect indefinitely among the ranks of the Galactic Empire's newly christened stormtroopers.
Still, Finn's increasing Force-sensitivity proved essential during the Battle of Exegol, and he's also clearly cultivated a Force bond with Rey. All this appears to set Finn up as one of Rey's first Jedi Padawans, training under her in order to master the Force.
Over the next decade, the galaxy was on the verge of civil war with entire star systems—led by Count Dooku, Yoda's one-time Padawan—threatening to secede from the Republic by 22 BBY.
Only Anakin Skywalker was ever “officially” a Padawan. So Anakin at age 9 was the oldest when he actually became one in Episode I. Luke was 19 when he began training under Obi Wan Kenobi in Episode IV but was never declared a padawan.
Some clones disobeyed the infamous order than decimated the Jedi order, and refused to execute it. SOME of these Clones include; Captain Rex: Captain Rex, as most know removed his chip that would later be the way that Palpatine would execute order 66. Wolffe: As with Captain Rex Wolffe removed his bio chip.
While Yoda sensed that the Sith's plan involved the Clones, it was too late to prevent Order 66. Instead, he placed his faith in the Force and allowed the dark events to happen.
Order 99 was an order arranged by Jedi Master CaptainR1. It turned the storm troopers back to side of the new Republic. During the clone wars, clone commando "Roger" refused Order 66. He was very close to the Jedi he was fighting with.
Anakin Skywalker's attachment to his wife, Padmé Amidala, was the catalyst for his conversion to the dark side. Living beings tended to mistake attachment for love, whereas attachment was possession and as such, like everything of the dark side, had selfishness at its core.
Kirlocca, Lowbacca, and Tyvokka are the only existing Wookiee Jedi characters (though an unnamed Wookiee in Edge of Victory: Conquest appears to be an unknown Jedi student rather than Lowbacca), as they were developed before this policy was enacted.
As both a Sith and the ruler of the Empire, Palpatine took advantage of his clone resources by indoctrinating them with an order to kill Vader. Order 151 is also a credit to the incredible fighting prowess of Clone Troopers, even with their free will removed.
Captain Rex's original story revealed that the fan-favorite Clone Trooper never followed Order 66 since he removed his control chip sometime between the death of ARC Trooper Fives and the Siege of Mandalore.
In his story, Maul poses as a member of a criminal cartel to kill a Force-sensitive thief for Darth Sidious, and experiences a vision of an alternate life as a peace-keeping Jedi, which he denies, much to Sidious' content. The story takes place shortly before The Phantom Menace.
Like all in the Order, the young Korun boy was taught by Grand Master Yoda when he was a learner, and eventually went on to become a Padawan to another Jedi. At one point during his apprenticeship, Windu trained under Master T'ra Saa.
The Mandalorian reunites with the Armorer and fellow Tribe member Paz Vizsla at their new enclave and recounts his adventures to the Armorer, who explains the Darksaber's history to him and begins training him on properly using the black-bladed lightsaber.
