vibrant = radiant < bright < brilliant
But, their meanings can be quite different. Vibrant is often used to convey charisma. Radiant is often used to convey spreading warmth or benevolent messages. Bright often refers to an individual's cognitive capacity & awareness. Brilliant often refers to performance in a particular task.
object < resist = oppose = protest
Note that the last three all have quite different meanings - in some contexts they can be stronger, and in other contexts they can be softer. Also note, I've never heard the word demur in my life, so can't include that word in these rankings.
grow = develop < bloom < thrive = prosper < flourish
Again, these words each have their own meaning. But in so far as they can share meaning, here's how I rate them.
