Actually no. Being the original prime field device does not mean that Noel isn't a clone. The Prime field device could have had it's core replaced many times as far as we know, and there is nothing that states that you can't use a clone as the core.

Since Saya is Ragna and Jin's sister, the only way for Noel not to be a clone of Saya, would be if all three siblings were clones of Noel.
