>how can I make it so one object is lit by an individual light source unique to that object?
Light linking is the term you're looking for, I think. Should be default in stuff like Max/Maya, and was recently added to Blender. You're essentially just telling the light to "only shine on this one object/group and nothing else".

>how would one replicate the corona and massive glare
If you're using Blender, you can take a volumetric shader, use a spherical gradient to turn it into a sphere, and then use masking techniques to do the little tendrils and shit.
For the glare/glow, you can use a cryptomatte layer in the compositor to select which objects get used for the glow.
Or just turn bloom on if you're using Eevee.
