Answer for clue #2

The chalkboard gives you 6 numbers in row A (the clue implies you need “A row”). Those numbers are shift numbers for each of the letters on the clue. For instance, the first letter on the clue is L, the first number in the row on the chalkboard is 1. If you shift the letter L over 1 space in the alphabet, you get the letter M. Do this for all of the letters, you’ll get the word MIRROR.

The answer is MIRROR.
