How do you open the locks on Raven the Secret Temple

I have found and tried two combinations one is of words that are highlighted in blue in the book, these words are: tree, stars and tiger. The second is at the temple of the moons on the floor at the bottom near the centre is a coin if you roll over it, it should get bigger, it should show 3 symbols, one of them being a four-point star.

I hope this was helpful, I only found the two - still trying to find the third combo. Good Luck!
