Nah it’s a glass something that has to do with electricity but I forgot what

Is the last pic the criticality blue glow from reactors?

Just plain old blue electrical arcs.
On the other hand, Cherenkov radiatiation is only indirectly related to criticality. It comes from any particle moving through a medium, generally water, faster than light travels through that medium. A luminous sonic boom of sorts! It’s associated with criticality because those are the contexts where it happens often enough to actually be visible.

Ah, it’s a photo of a mercury arc rectifier (which is more electrical engineering, maybe?), not, Cherenkov radiation.

“Mercury” and “arc” on the same sentence do really, really not make one imagine something that perfectly fine to use or be around in operation.
