On the final scene from 'Rise of Skywalker' the new lightsaber we see used by Rey was her very own lightsaber. We can confirm this because the saber was created from her Staff that she used throughout the Sequel Trilogy.
What was the significance of Rey having a yellow lightsaber at the end of Rise of Skywalker? Well in Kotor Yellow represented the Jedi Sentinel which is a Jedi who is more intellectually skilled (Hacking computers, Repair droids and computer consoles etc.) which makes sense due to her scavenger upbringing on Jakku.
Traditionally, yellow lightsabers are associated with Jedi Sentinels, who balance their combat skills with a strong focus on exploration and practical application of the Force. This choice reflects Rey's well-rounded training and her determination to maintain balance in the Force.
Whose Lightsaber Does Rey Have at the End of The Rise of Skywalker? In addition to her own yellow lightsaber, Rey Skywalker has Leia's lightsaber and the Skywalker lightsaber (which belonged to Anakin, Luke and Rey herself) at the end of The Rise of Skywalker.
How does Rey have Anakin's lightsaber in episode 9?
Skywalker lightsaber
The lightsaber then became part of Maz Kanata's collection of Jedi curios, where it called to the scavenger Rey. She wielded it in defeating Kylo Ren, then brought it to Ahch-To and offered it back to Luke. When he refused it, Rey carried the ancient weapon herself.
Terrio describes Rey's journey to Tatooine as a pilgrimage honoring the Skywalker family heritage, saying: “Rey brings the sabers there to honor the Skywalker twins by laying them to rest—together, finally—where it all began.
The fate of Luke Skywalker's old lightsaber appeared to be symbolic of his philosophy; it was shattered in a Force tug-of-war between Rey and Kylo Ren. Even its Kyber Crystal was broken. And yet, in spite of that, Rey succeeded in repairing the lightsaber in Star Wars: The Rise of Skywalker.
Despite being enemies, Rey and Kylo Ren share a connection called a 'Force dyad' and eventually become romantically involved with one another. Following Palpatine's final defeat and her own resurrection, Rey adopts the name Rey Skywalker to honor her mentors and their family legacy and renounce her lineage.
Rey Skywalker, known only as Rey throughout the First Order-Resistance War, was a human female Jedi Master who fought on the side of the Resistance during the war. A former scavenger from the planet Jakku, her life was changed by the tumultuous events of the last days of the New Republic Era.
This explains why Rey could hear the lightsaber "calling" to her in Star Wars: The Force Awakens; she was destined to join herself to the same Skywalker legacy, and thus she was sensing echoes of Anakin and Luke beckoning her to them.
The black lightsaber, or Darksaber to give it its proper name, is one of the rarest lightsabers in Star Wars canon. Despite its rarity in canon, anyone who has seen the second season of The Mandalorian is likely to be familiar with the Darksaber.
Purple itself is considered the most powerful lightsaber color in the Star Wars galaxy. Very few Jedi have ever wielded a lightsaber of this color. The only two people known to have wielded a purple lightsaber are Mace Windu and Darth Revan in the past.
Rey Repaired Anakin's Lightsaber - And Bonded With The Crystal. After Luke lost Anakin's lightsaber, it somehow ended up in the hands of Maz Kanata which in turn was given to Rey years later in The Force Awakens.
The gold-hilted lightsaber is a type of lightsaber that was wielded by sinister Jedi Moon Ni Rin during the Clone Wars era. It had a gold hilt and blue-blade.
Poe gave BB-8 the map revealing the whereabouts to Luke Skywalker before the pilot was captured by the First Order. The droid was also taken hostage on Jakku by a scavenger before being rescued by Rey. BB-8 then stood by Rey's side, trusting her for the duration of the trilogy.
Rey was powerful with the Force, as anyone from Palpatine's bloodline would be, but it's highly doubtful she was anywhere near as powerful as Anakin Skywalker.
Admittedly, Rey skills couldn't possibly be as developed as Anakin's or Luke's. Nevertheless, considering how fast of a learner she is, and how unique the powers she possesses are, it's not a stretch to say that Rey could be a more powerful Jedi than Anakin and Luke Skywalker.
While the Skywalker bloodline is technically gone, Rey honors her fallen mentors, Luke and Leia, by adopting their family name. When asked who she is by the old woman on Tatooine, the former Palpatine declares herself Rey Skywalker, and she becomes a new part of the family.
He was incredibly important, both to the galaxy as a whole and to Rey personally. While they may not have had romantic love for each other, they became close enough that Rey would miss him after his death. The kiss at the end of The Rise of Skywalker was a goodbye to a friend who would be dearly missed.
Finally, Rey is Kylo Ren's aunt through Anakin Skywalker. This means that Kylo and Rey's romance is just as genetically awkward as Luke and Leia's kiss on Hoth was. Granted, neither pair knew they were related at the time, but that's no excuse.
Luke's words confirm that Leia discovered Rey was a Palpatine during her lifetime, either before or during the time jump between The Last Jedi and The Rise of Skywalker. If Luke found out through his Sith investigations, or while training Rey on Ahch-To, he undoubtedly would've passed on this knowledge to his sister.
Kylo develops a close relationship with Rey and starts feeling genuine affection towards her, so when Snoke reveals that he had manipulated their bond and tortures her in front of Ren, he looks furious at his master. Thus, when Snoke orders Ren to kill Rey, he chooses to save her and kill his master instead.
Kylo Ren's "unstable" lightsaber was designed to kill. Knowing Makashi, he would become a much more dangerous foe as he could disarm and eliminate his opponents far quicker without the need to endure a long, intense fight. Sadly, he didn't learn Form II as there was no one around to teach him during his younger days.
