May I know what's the difference between the star ratings ?

I have no idea what makes a 1 star bumblebee different from a 2 star one.

If there's an explanation in the game I have missed it out completely and can't seem to find it .

Any help would be great thanks.

Higher star ratings higher their base stats are and higher they can rank

Sunburner

the higher ones def have better stats and I think starting at 3 & 4 they have more powered abilities (the bar at the bottom) max is 3 bars though (if it's anything similar to Marvel Champions)
