No, Elrond is not the oldest elf; he's quite young compared to others like Círdan the Shipwright, who is considered the oldest in Middle-earth, and even Galadriel, who was born much earlier in the Years of the Trees, making her thousands of years older than Elrond, who was born near the end of the First Age.
IIRC Cirdan is the oldest known elf. It's possible (though unlikely) that he might have not been the oldest elf of his people despite being their leader.
Elrond's was born nearly 600 years after Galadriel, but he was born as a half-elf, and so until he made the choice to become an elf, he aged at a faster rate, though still slower than mortals.
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.
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.
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.
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.

His true age isn't precisely stated, but he was around long before time was measured in Middle-earth, so thinking in tens of thousands of years isn't far off. It's Tolkien's way of emphasizing Gandalf's timelessness and deep knowledge.
Legolas is introduced at the Council of Elrond in Rivendell, where he came as a messenger from his father to discuss Gollum's escape from their guard.
Indeed, it seems Elrond used this The Rings of Power kiss not to admit his true feelings for Galadriel but so that he could slip her a pin from his cloak.
Gandalf specifically says Treebeard is "the oldest living thing that still walks beneath the Sun upon this Middle-earth." Just fun to remember there are trees older than any non-Ainur living thing.

Puberty and full height are attained at around their fiftieth to one hundredth year, when they stop aging physically. Elves marry freely, monogamously, only once, and for love early in life; adultery is unthinkable.
