Freya Mikaelson is the eldest daughter of Mikael and Esther, making her a firstborn child and member of the Original Family. She had two siblings,
Elijah was born between October 977 to early 978 making him at most 24. Klaus is about 3-4 years younger and according to a s2 flashback on tvd he was possibly born around March (but that could be ignored) making him at most 20, since if Elijah is 24 he would have just turned so.
Elijah Mikaelson is the second-oldest of the Original vampire brothers (and the third-born child of Mikael and Esther).
Mikael is the eldest as he turned first! Rebekah was the first to change out off all the original siblings!
Kol is the older brother of Rebekah. He seems to be a year or two older than her. Since Henrik died, they are the youngest Mikaelson siblings. It is seen that Kol and Rebekah are partners in crime whenever they have been on screen together.
Freya is the firstborn child of Mikael and Esther, the elder sister of Finn, Elijah, Kol, Rebekah, and Henrik, the maternal older half-sister of Klaus.
Henrik Mikaelson: Henrik was the last and seventh born child of Mikael and Esther, the younger brother of Freya, Finn, Elijah, Kol and Rebekah and the younger half-brother of Niklaus. Henrik was the youngest sibling and child of the Original family.
Olympia Elisabet Nikole Mikaelson is a siphoner-vampire-werewolf mortal tribrid. She is the only biological child and the younger daughter of the original vampire, Elijah Mikaelson and the original immortal tribrid, Dianna Mikaelsson. She is the adoptive younger sister of Saga Mikaelssen.
While Klaus was the Mikaelson that was shown to have the biggest hold on the lives of the others, he was actually their half-sibling, a product of their mother's infidelity. He was also the middle sibling — Freya, Finn, and Elijah were older than him, while Kol, Rebekah, and Henrik were younger.
The writers usually spell out things that important “originals grow stronger with age”, but they never did because originals are already the strongest they could ever be. Only modifications enhances them. The spell just made them more resilient and able to compel their progeny, it didnt put them at peak.
The vampires who have been called Originals are: Mikael, Finn, Elijah, Klaus, Kol and Rebekah. The Originals are legendary throughout the supernatural world, especially amongst witches and vampires due to the fact that they have walked the Earth for over a thousand years.
Even though Klaus will go down as one of the most powerful vampires in television history, there are plenty of TV vampires from other TV shows (and some from his own) that are stronger than the Original Vampire. Hope Mikaelson ended up being one of the most powerful supernatural beings in the Tvd universe.
In the Original family, Klaus michaelson is undoubtedly the strongest because he is a hybrid vampire. He has the power of the Vampires(an original vampire) and the power of werewolves. Unlike werewolves, he can make his bite dangerous at any time. He has his powers enhanced because of his hybrid character.
1/2 Werewolf, 1/4 Vampire, 1/4 Witch
Hope Mikaelson is the only surviving example of this variation of Mortal Tribrid. She received 1/4 Vampire, 1/4 Werewolf, and 1/4 Witch from her father (Niklaus Mikaelson) and 1/4 Werewolf from her mother (Hayley Marshall-Kenner).

Sage Maria Mikaelson (née Benedici) is a vampire and the wife of Finn Mikaelson. She is the daughter-in-law of Esther Mikaelson and Mikael Agnarsson through her marriage.
With all of this in mind, it is important to note that Rebekah is the weakest Original Vampire, I wouldn't necessarily say because she's female, but for the sake of this argument, it's worth noting this, but at the end of the day she might have simply been the weakest child of Esther (strength-wise), and not because ...
Finn chastised Klaus for his treatment of him, and questioned why he left him daggered in a coffin for nine hundred years. Klaus claimed it was because Finn was a sycophant and then told him he had made a mistake in coming back as a witch rather than a vampire, since he was easier to kill.
In addition to her background, Freya is the best because she is the only Mikaleson with no hatred towards any of her siblings or parents. Unlike Elijah, whose familial duties are tailored only towards Klaus and Rebekah, Freya is for everyone, especially Finn and Kol, who are mostly neglected.
Following these events, Dahlia crafted the Immortality Slumber Spell, in hopes of eventually achieving true immortality while also retaining her magic. Despite Freya's protests, she performed the spell on herself and her niece, thus condemning them both to sleep for a 100 years and be awake only one year per century.
Nikolaus Mikaelson is an Witch-Vampire Hybrid. He is the son of Marcellus Mikaelson and Rebekah Mikaelson.
Physically as of now, Marcel is stronger because of Lucien's werewolf toxin serum. Basically, Marcel is an original vampire who also has werewolf venom in his bite that even Klaus can't heal. So he has them all running scared.
