Oh, yes, Alabaster is a little bit hudge
Let's begin with the last picture.
It is the Animal Palace. You see 12 (13) animal symbols. These animals are scattered throughout the island. Each animal is assigned a D'ni number.
If you have all the animals (numbers) together you get a code and can open the Palace.
So you see D'ni 4. Push it, you will hear something. Go to the top of the mountain, and you see what it mean. Thats your animal number 4.
Now to the first question. What is this switch. You can push it, something happens, but you do not see what. Go on this field. near a round stone. A D'ni number ?
Then find the way on these bridge (may be it cost you a long time),

you reach it after solving the beetle puzzle
but then you will see what this switch will do. You can see it only from the top.
Maybe another animal?
Third question: To solve the beetle puzzle you need a hint.
This hint you find near the animal Palace. Go down stairs to the big door. In this room you find more hints.

The hint for the beetles you find in the bethroom.
One hint you need for the Eyes Puzzle. The Eyes Puzzle (you reach it after swim a long time in the green water) is also the answer for your next question.
"Cannot reach the Journey cloth"
Swim to the "Eyes Palace" and you will reach it. If you are there, open the door
- Show Spoiler
Look around to the eyes on the wall. Maybe one have a hotspot. Look outside on the stair the big eye will give you a hint.
Next question:
"Puzzle, shapes"
I call it Feather Puzzle. You can solve it, if you have the hint. This hint you will get after solving the beetle Puzzle.
So dont worry. All in his time.
"Cage" Do not know the cage
Is it from me ?
Never give up
