As Cam says, these are generally all X-Plane limitations or "features". The blurring of 3D cockpit panels comes from a blooming effect and should reduce with brightness, from what I understand.
These are rendered directly by the Challenger itself, so don't get affected by X-Plane effects.
These are both likely artifacts of the way X-Plane does screen-space reflections, and there's nothing an addon developer can do about it.
This is again an X-Plane effect. It's simulating the brightness of displays being overwhelming for one's eyes at night time. The answer, again as Cam said, is to reduce the brightness to very low, as one would need to do in real life. (The effect isn't perfect, it's probably a bit overdone, but it is what it is.)
Possibly turning down texture quality one notch, depending on how much VRAM your GPU has. But, probably not.
