I shave every day, but my beard stays the same. What am I?

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

I am first found in caves, now prolific online; I am a depiction, a drawing, a symbol, or sign. I will convey whichever mood you could wish; or for that matter, a fist, flask, or fish. What am I?

A finger goes in me. You fiddle with me when you're bored. The best man always has me first. 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 have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I?

There was a greenhouse.
Inside the greenhouse, there is a white house.
Inside the white house, there is a red house.
Inside the red house, there are lots of babies.

What is It?

I come in different shapes and sizes.
Parts of me are curved, other parts are straight.
You can put me anywhere you like,
but there is only one right place for me.
What am I?

Two in a corner, one in a room, zero in a house, but one in a shelter. What am I?

When it is alive we sing, when it is dead we clap our hands. What is it?
