Who has married many women but was never married?

Take one out and scratch my head, I am now black but once was red. What am I?

You measure my life in hours
I serve you by expiring
I vanish faster when I am thin
and slower when I am thick
The wind is my energy
What am I?

I’m tall when I’m young, and I’m short when I’m old. What am I?

You see me once in June, twice in November, and not at all in May. What am I?

A father's child, a mother's child, yet no one's son.

Who am I?

You can win me and lose me but never buy me
You can not eat me and never want to part with me
I can make you cry or bring you joy
I am not a machine and definitely not a toy
You keep me but i am not forever just yours
You might find me in a case or on a shelf next to a vase
I am hard and i am tall if you bump me i am sure to fall
I am made of different materials and am at many events
If your lucky and fight hard I might be yours
What am I ?

I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I?

I make a loud sound when I’m changing. When I do change, I get bigger but weigh less. What am I?

If your uncle’s sister is not your aunt, what relation is she to you?
