Is it primarily useful? Decorative?

Do you tend to find it indoors? In a particular room? Kitchen? Bedroom? Bathroom? Living room?

Yes, I'd say it is primarily useful, but some are very decorative.

Well, indoors is where you usually find them, but I'd say most spend at least a little time outdoors.

At my house, the least likely place to find one of these is in the bathroom.

Is it edible? Is it delicious?

Yes, you can hold one of these in your hands.

Do you think if I need a basin to hold all of these?

It is not edible.  If you tried to eat one of these, I doubt that it would do you any harm, but I certainly would not expect it to taste good.
I'd say most people have special containers that hold a lot of these. 
It is possible to hold quite few of these in your hand.

Does it require batteries?

Is it made mostly of wood? Of metal? Or maybe glass?

Nope, they don't need batteries.

They're not made of wood per se, but wood is usually the raw material used to make them.
No metal, no glass.
