I'm not number one and I'm not number three, sit on a throne and below I will be. What am I?

I grow yet I'm not a plant, i have brothers in great numbers, some short, some tall, and we all age until we are grey

You've beaten me, you've battered me but I won't fall to you. Leave me be, I'll rise up high and in flames, be born anew

When it rains I grow in size. When it's dry I stay inside. I have no bones, but do have ribs. Use me in sun and I have a different name.

I pierce and hold a wooden beam, or am painted with polish to shine and gleam. I protect your fingers, yet can fasten a brace, I’m found on walls or on a fingertip’s space.
