Do You See It?

I’m light as a feather, yet the strongest person can’t hold me for five minutes. What am I?

I came first on earth but second on the heaven.
I also came twice in a week but found just once in a year.
I stay away from months but you can find me in February.

What am I?

I possess a head

I flaunt a tail

But I don't have mouth or legs

Can you find out who I am?

A certain street contains 100 buildings. They are numbered from 1 to 100. How many 9's are used in these numbers?

I look flat, but I am deep. Hidden realms I shelter. Lives I take, but the food I offer. At times I am beautiful. I can be calm, angry, and turbulent. I have no heart but offer pleasure as well as death. No man can own me, yet I encompass what all men must have. What am I?

What is more useful when it is broken?

I am soft and cuddly that soothe your heart. But, If you pick my last name I am going to tear you all apart. Who am I?

If,

A = 1

B = 2

C = 3

...

...

Z = 26.

Based on above rule, you need to find an eleven letter word whose letter sum is equal to 52.

I’m orange, I wear a green hat and I sound like a parrot. What am I?
