I'll start by saying that I am no expert in Kabbalah and this is a topic which has roots in deep Jewish mysticism that I am not equipped to answer. However, I can at least provide the bare bones of an answer, at least on a very simple level.
In Wikipedia here it talks about a practical Kabbalah sefer known as Bris Menuchah authored by 13th Century Kabbalist, Rabbi Abraham ben Isaac of Granada.
This book apparently features plenty of references to angels one of which is Nuriel.
On this page the book mentions a series of angels and their various roles. It mentions Nuriel:
It describes him as the angel whose remit is "ועל אבני אלגביש ממונה" - i.e. that he is G-d's agent over hailstones.
When digging a little bit, Rabbeinu Bachya writes extensively about the large number of angels that accompanied the Bnei Yisroel upon their exit from Egypt and their arrival at the foot of Har Sinai. One excerpt sheds some interesting light (note this is in the Sefaria translation and is an addition to the actual text):
Five major angels named אוריאל, רפאל, גבריאל, מיכאל, (נוריאל) were seen by the Israelites at that time, the first four representing whole encampments surrounding the Shechinah and presided over by the fifth angel נוריאל who “rode” above the others.
So according to this understanding of Rabbeinu Bachya, it would seem that he is regarded as one of the 'major' angels.
Indeed, his appearance amongst the other perhaps more 'well-known' angels would seem to verify this point here in the Zohar 3:227
