Sauron and Gandalf were both Maiar: a supernatural race that serve the Valar, and many Maiar assumed different forms. Gandalf is one of five Wizards, a group of Maiar originally sent to Middle-earth by the Valar to aid the resistance against Sauron, and were given the appearance of old men.
Although he is from the same race as the five wizards (Istari) he was not one of them. Both Sauron and the five wizards were Maiar, a part of the race known as the Ainur.
Although the finale, “Alloyed,” opens with the reveal that the Stranger is Sauron, that's a fakeout, and the trio of white-cloaked women who were after him was mistaken. We later learn that Halbrand is Sauron, while the Stranger is one of the Istari — the formal name for wizards in Middle-earth.

Is Gandalf afraid of Sauron?
Take note, then, that at the root of Gandalf's quest is fear -fear of Sauron in particular. We are not told exactly why -but Sauron is a fellow Maiar, an angelic being who chose to follow Morgoth at the beginning.
A thousand years before the events of the War of the Ring, yet a thousand years after his arrival in Middle-earth, Gandalf once entered Dol Guldur, alone, and indirectly challenged the Necromancer. Sauron, who was then still growing in strength, had not yet power to challenge him (though he had alrea…
Though wizards are technically Maiar, they do not possess all the same abilities in their wizard forms. This is why, despite Balrogs and Sauron also being Maiar, Gandalf wasn't evenly matched in his wizarding form—especially as Gandalf the Grey.
Bloodlines are very important in Tolkien's stories, and it makes a lot of sense that Sauron would fear the great-grandson of the man who cut off his hand. Aragorn carried the blood of Numenor with him. His genetic connection to the heroes of the Second Age established him as a dangerous opponent of Sauron.
Sauron was the most powerful of the Maiar—primordial spirits created to help the Valar first shape the World. His original name was Mairon, which means "the Admirable," and as an immortal spirit born before the world's creation, he was able to perceive the Creator Eru Ilúvatar directly.
"So I think in his pitch to Galadriel, it cannot mean that he loves her or that there's any kind of romantic relationship. There should be no ambiguity around the fact that Sauron is evil — he's terrible, and he's using Galadriel to enhance his power."
Meanwhile, a few faithful Númenóreans, led by Elendil, were saved from the flood, and they founded Gondor and Arnor in Middle-earth. Sauron still considered them his hated enemies and he launched a pre-emptive attack on Gondor in S.A. 3429.
Sauron was originally a shape-shifting fallen angel and could take on various forms, including a vampire and a werewolf. Sauron's final form was terrifying and demonic, reflecting his own hate and evil, and he did not wear armor in the books.
Additionally, while he was in his weakened state, Galadriel could hold him off through the power of will alone. However, if Sauron had his One Ring and faced off in a battle against Galadriel, it's unlikely that there would be much she could do.
Finally Sauron came out to fight Elendil and Gil-galad face to face. When Elendil fell, his sword Narsil broke beneath him. Isildur took up the hilt-shard of Narsil and cut the One Ring from Sauron's hand, vanquishing Sauron.
Summary. Gandalf's claim to be Saruman when he returned in The Two Towers was because his resurrection as Gandalf the White meant he had taken on the role and form of the White Wizard. The wizards in Middle-earth were avatars or incarnations of the powerful Maiar beings, with Saruman as the leader.
In his notes, Tolkien remarks that Sauron saw Galadriel as his equal. Add that to the fact that she's untrusting of Sauron (yes, even when he's in his Annatar guise) and an unwavering, single-minded force, and it's more likely than not that Sauron feared Galadriel — or the potential she held to upend his plans.
Although Sauron's origins are angelic, he becomes captivated by the idea of ordering things as per his own will, which might be a possible reason behind him being lured by Morgoth, a Dark Lord who corrupted countless souls and waged wars against Elves and Men throughout the First Age.
Morgoth, the first to reign terror upon Middle-earth, was more powerful than Sauron and commanded an army of dragons and Balrogs. While both Morgoth and Sauron were cunning, Morgoth's rule and terror lasted longer and his corruption spread further, making him more formidable in the Lord of the Rings universe.
He will fight in the Last Battle against the Valar and their allies, but will ultimately be slain by Túrin Turambar, the Man he cursed. By finally defeating Morgoth, Túrin will avenge not only himself, but all members of the race of Men.
NO, Sauron was so much more powerful than Gandalf. Had all the 5 Ishtari worked together they could not have defeated Sauron in combat. Besides they were forbidden by the Valar from doing so. Their mission was to raly the Free Peoples to fight against Sauron and his minions.
Sauron seemed to genuinely feel a connection to her, and part of that came from sensing the darkness inside of Galadriel. In that regard, his offer was really a seduction to the dark side.
"She's helped to save him," Clark said. "She's also inspired him, and she'll always know that." After Galadriel makes it clear to Halbrand that she knows he is Sauron, he makes a pitch for her to join him. Halbrand says Galadriel can become his queen, and that she will bind him to light while he will bind her to power.
