Please, do read over the two documents I've attached in this post.

-How old was Ciel when she created Copy X?
HONDA: We made it so that Ciel herself was a product of the technological advancements of Neo Arcadia. With the dream of creating a utopia for humans and the Reploids sworn to protect those humans, researchers were working on producing humans with altered DNA. In the process, some children were born for the specific purpose of developing better Reploids to assist in this research. Ciel was just one of these children, and was a prodigy. Just by watching and mimicking the experiments, she somehow managed to produce Copy X. This let us explain how Ciel could have been Copy X's creator.
AIZU: She was nine years old at the time.HONDA: That sounds about right.
-WHAT ARE THOSE FREAKIN CYCLOP-X-LOOK-ALIKE ROBOTS CALLED?!
ZERO3 has this convenient in game chip database with the names of all enemies.
And they (the Pantheons) are Repliroids. Mass-produced mentally degraded Repliroid copies of X.
-What was Kraft doing, before Vile appeared?
The most accepted name is "Craft". Saying "Kraft" is akin to saying "Bile". The Complete Works adheres to Vile and Craft. Craft's activities before Dr. Vile's Ragnarok Strategy are explained in great depth in -Vile's Incident-.
Also, it would not make much sense that the Weil Numbers had become the Eight Judges after the war.
They weren't Vile Numbers until after Vile's return in ZERO3 and him altering both their bodies and minds. Before that, there history is largely unknown, we do not know if the Mythos Repliroids that became the Eight Judges were alive during the Elf Wars, we only know that some of them (Blazin' Flizard) had other occupations.
I actually remember discussing the whole Neo Arcadia government thing here a while ago, so it mostly matches my blurred memories.
My guess is that since there was a peaceful period before the Elf Wars, Neo Arcadia as a metropolis was created at that time. Weil was reported to have been 'banished' from Neo Arcadia after the war, which makes it sound like it already existed before his rebellion.
The exact details on Neo Arcadia's time founding is something that warrants severely lengthy walls of text. Related to that are the equally complicated of the Yggdrasil seal and the creation of Neo Arcadia's Four Guardians.
The 'city of Neo Arcadia' was created by X 'at the center of rebirth' to 'walk on the path to recovery'. X was said to have founded Neo Arcadia after he ended the Irregular Wars and after the Elf Wars.
The existence of 'Neo Arcadia' prior to that city's founding is a complicated matter not solely about Vile being a Neo Arcadian scientist. The remnants of Vile's laboratory has the logo of Neo Arcadia, a similar logo is present on Vile's rejuvenating armor. Furthermore, Vile's Incident referred to the government of that time as 'that Neo Arcadia'. The existence Four Great Forests 'that surround Neo Arcadia' and hold ruins of the civilizations of before Neo Arcadia in which Repliroid research was carried out but in truth hide the dirty secrets of the Elf Wars is also something that raises many questions.
It is my own personal opinion that the project to create the utopia Neo Arcadia began after the completion of Project Elpis; when X ended the war and the world started recovering. That project would have been interrupted by the Elf Wars. It is the 'Neo Arcadian' government of that time that facilitated the creation of Dr. Vile's Omega for the sake of ending the war, but was betrayed by Vile. To protect their own reputation the truth behind that man's sin was hidden away and the established Neo Arcadia came to have a centennial history of bloodshed and lies; built upon those that lost their lives in the worst war in history.
