You will use the Ice Arrow, but you can only shoot into the dragon's mouth, and only when it is "asleep" for a moment. This involves going over the dragon then throwing the lever on its back, and you have to do this three times.
The basic steps:
Further Detail
As soon as you enter the lair, climb the chains and work your way across the top. If you are high enough, it is quicker to jump sideways than climbing every chain. If you approach from behind, you won't be zapped. Dodge the spike ball at his tail and reach the lever on his back. (*The lever must be in the back position and the spike ball working.*) Throwing the switch will put him to "sleep" for JUST A FEW SECONDS. VERY QUICKLY jump in front of him and fire the Ice Arrow directly into his mouth. (This should make him flash red and jump up and down.) Repeat the same thing twice more, but now it is complicated by dodging falling stalactites from the ceiling. You can likely survive one miss without failing the round.
* The dragon falls down below, but the Princess isn't there, so you have to search for her on the other planets
No. (see related question)
you need to defeat the dragon
no
You dodge the ball.
You pull the lever to make the dragon fall asleep and then, in the short time you have, you have to fire the arrows in his mouth. You have to do that 3 times and then you have defeated him.

There is no treasure chest on Astro Knights Island.
You don't defeat knights, you talk to them and they'll give you a weapon to defeat a beast. (On the jungle planet, find the Laser Lance down in the plants before you meet Sir Cador.)
You must defeat all three planets (tigercopter, phoenix birds, and dragon) to advance to the end of the game. When all three knights are accompanying you, you can find the Princess using the Golden Key on the secret giant asteroid. (see related question)
