Your Google Drive link is invite only.

Hard to tell by just looking at the picture. Did you set all light emitters to the same sample rate? You'll get crazy noise pollution if you don't.
For dark scenes I usually set mine to 10 000 and then render between 6000 - 10000.

evenly light the scene with lots of light, bring down the exposure to taste. Also, take GI clamp way down. Try 1 first.

I discovered a mistake from my side, the specular material of the pricipal lights was a C4D material.
After replace this with an octane specular one, it's better.

I've some noise but less !
