Hi Zamm, I'm back again.
Like Malcdelsol said, there are hints to some of the levels you asked about on the Midnight Synergy website. It has hints for the Classic (at the top)and Deluxe (after the Classic hints) games. If you don't know where that is, here is the link:

I'm a little confused about the level you called "Water, Water Everywhere". There is not an ice rink in the one I found in the tutorials. Could you give the world # and the Level #, rather than the name?
For the one called "collaboration".
SPOILER AHEAD
For teaching purposes, they colored some tiles gray/black. You need to move one of the characters ahead to the colored tile which the other character pushes the box to a position in front of the character on the colored tile. The character on the colored tile can then push the box forward. Be sure to have one character ahead so they can be positioned on the next colored tile.
