No, Elrond is significantly older than Legolas, as Elrond was born in the First Age (around 6,500 years old), while Legolas's age is unknown but he likely lived much of his life in the Third Age, making him hundreds to perhaps a couple thousand years old, but still younger than Elrond. Legolas's father, Thranduil, lived through the First Age, but Legolas himself seems to have only experienced the Third Age and beyond, suggesting he's younger than Elrond, who was present at events like the Last Alliance.
Legolas calls the other members of the Fellowship "children," indicating his advanced age. Still, he is never mentioned as having fought in The Last Alliance, which means he is not as old as Elrond.
Legolas was the son of Thranduil, the King of the Elves of Northern Mirkwood. His mother is unknown. Legolas came to the Council of Elrond in Rivendell, the great meeting held by the Elf lord Elrond, as a messenger from his father to discuss the escape of Gollum.
Gil-Galad and Thranduil would be around the same age since they both were born during the First Age. Behind them would be Elrond who was born near the end of the First Age.
Arwen married Aragorn in the year 3019 of the Third Age, when he was 88 years old and she was 2,778 years old. The last year of the Third Age was 3021. Aragorn ruled until the year 120 of the Fourth Age, when he was 210 years old.
It's not the years; it's the mileage. Gandalf isn't a Maia in the same way Sauron is. He was sent to middle earth as an old man, so his body is much more real than Sauron's “raiment”. He can't use his power to the same extent, he can't change his forms at will.
The movie the Battle of Five Armies expanded on Tolkien's canon by saying that the white gems Thranduil wanted back from the dwarves were originally intended for her, but that she was captured and taken and tortured to death by Gundabad orcs before the order was completed.
Unfinished Tales explains that Radagast, like the other Wizards, came from Valinor around the year 1000 of the Third Age of Middle-earth and was one of the angelic Maiar.
Everyone is going to have a different answer but, for elves, I assume this: The human equivalent is x5 up to 'mid-twenties' bracket. So, a '16yo' is 80 years while a '24yo' is 120 years. After that, the aging process essentially stops.
Therefore it is feasible that he would have never actually had a wound before, especially as it took all that from Bolg to get the smallest nosebleed. Therefore seeing his own blood came as quite a shock. And demonstrated the violent nature of his foe to both Legolas and the audience.
Though Dwarves and Elves are traditionally rivals, he and the Dwarf Gimli form a close friendship during their travels together.
Valinor. In Valinor, Gandalf, a Maia, was named Olórin, one of the people of the Vala Manwë, and the wisest of the Maiar. He was closely associated with two other Valar: Irmo, in whose gardens he lived, and Nienna, the patron of mercy, who gave him tutelage.
He can't simply leave Galadriel to her fate, though. So, we must intuit that Elrond kissed Galadriel in order to distract Adar and the Uruk (who were so shocked that two characters who have no business kissing were kissing they forgot to pay attention) from the rest of what he was doing.
The Wizard clad in brown was Radagast and the one clad in grey was Gandalf, seemingly the oldest and the least of the Order. The other two who travelled to the East and South were sometimes said to clad themselves in robes of sea-blue and were known as the Blue Wizards.
Faramir lived to be 120 years old, due to the large percentage of pure Dúnedain ancestry he possessed as a member of the Gondorian nobility.
Frodo comes of age as Bilbo leaves the Shire. Frodo inherits Bag End and Bilbo's ring. Gandalf, uncertain about the origin of the ring, warns Frodo to avoid using it and to keep it secret. Frodo keeps it hidden for the next 17 years, and it gives him the same longevity and youthful appearance it had given Bilbo.
Gimli was 139 years old (born in 2879 of the Third Age) when the Fellowship of the Ring set out from Rivendell, making him 52 years older than Aragorn.
He attacks the Orcs in rage, and is later confronted by Bolg. He saves Tauriel from being attacked by Bolg, but is mortally wounded during the fight. Kíli dies with Tauriel by his side. Bolg is eventually killed by Legolas while Azog is killed by Thorin himself avenging the brothers.
After the battle and Thorin's death, Thranduil took Orcrist, which was previously confiscated in Mirkwood, and laid it upon Thorin's tomb. The treasure was divided among Elves and Men, and Thranduil received the emeralds of Girion.
She was captured and tormented, receiving a poisoned wound. Her sons rescued her and she was physically healed by Elrond, but never fully recovered in mind or spirit, and no longer wished to stay in Middle-earth. She left for the Grey Havens and passed over the Great Sea the following year.
To clarify: Tolkien is fairly clear that Fëanor had the greatest potential of any elf, ever.
The Ent who figures most prominently in the book is Treebeard, who is called the oldest creature in Middle-earth.
The Eru-begotten, otherwise known as the First Elves or Unbegotten, were the very first 144 Elves who were awakened by Ilúvatar on the shores of Cuiviénen during the First Age. Each of them slept beside his or her spouse, and there were 72 such pairs.
