Alright everybody, this time I looked specifically for hard riddles, so hopefully this one will not be a cakewalk. Let's go!

OK, let me try this without looking at any intervening posts first:

#1: I am something people love or hate. I change peoples appearances and thoughts. If a person takes care of themself I will go up even higher. To some people, I will fool them. To others, I am a mystery. Some people might want to try and hide me but I will show. No matter how hard people try I will never go down. What am I?

Spoiler: show

Age?

#2: Only one color, but not one size,
Stuck at the bottom, yet easily flies.
Present in sun, but not in rain,
Doing no harm, and feeling no pain.
What is it?

Spoiler: show

Shadow?

#3: Who is that with a neck and no head, two arms and no hands? What is it?

Spoiler: show

A turtleneck shirt or sweater?

#4: If eleven plus two equals one, what does nine plus five equal?

Spoiler: show

Two (o'clock, or modulo-12 arithmetic for us mathematicians).

#7: What is it that given one, you'll have either two or none?

Spoiler: show

Copies?
(Being given a photocopy of a paper of yours, you now have two copies, but given a copy of, say, a Rolex, you actually have no real Rolex.)

Spoiler: show

A twin?
(Given the presence of one, he's either your child and you have two, or someone else's.)
(Granted, it's ignoring the possibility that you had twins for children several times.)

I know its not the answer, but that occurred to me:

I have a couple too!

J1: Narrow sounds, long capes, rock at every end. What is it?

J2: When I carry you, you get tired but I don’t. Who am I?

J3: I have no mouth yet I speak, no ears yet I hear, and answer in all language of the world. Who am I?

J4: It can fit in through the window, but won’t exit through the door. What is it?

J5: All day I lie on my back, at night I stand upright.

These are “Finnish riddles” translated by yours truly. I don’t think most are particularly Finnish though
