#4 - Directly behind the location in which you obtain Minikit #3
#5 - Beyond the avalanche, after crossing the deep snow and building a narrow tunnel. It can be found in the left part of the cave.
You will need to hit a few things here as well. This time they will be pennants.
#1 - After crossing the second deep snow part
#2 - After going past the first camp and collecting your team, you will have to head left along the wall

After passing by the avalanche, you will find mithril rocks by the wall. Blow them up with the Berserker's bombs.

A bit behind the avalanche, after jumping across the gulf, you should see a hook on the wall. You need to climb up and change your character to Shagrat there.

After crossing the bridge, avoid the strong winds and instead of going up the stairs, move towards the camera. It can be found beside pennant #4.

Beneath three big rocks you will find three small stones. Pick them up and throw them at the bottles floating in the water.

In the left part of the map, around the middle of climbing with Legolas, you will find a dark cave. Change to Frodo and head inside it while lighting up the path with the Phial.
Inside you will have to approach a wall which can be climbed by Gollum. Climb it and change to Sam to start a fire. Now you will need to feed the Troll: Gimli has to break the ice and Gollum fish.
Take the fish to the Troll and the monster will spit the chest onto you.
Treasure: Ice Lolly
From where you fed the Troll, you have to move towards the camera, break the rocks and dig up the ground to pick up the treasure.
