Ratings: Is 1 being worst and 5 the best?

1 represents the lowest level of whatever variable you're tracking that you've ever experienced.

5 represents highest 
level of whatever variable you're tracking that you've ever experienced.

So whether 1 is worst or best depends on if the variable is a good thing or bad thing.  For instance, a rating of 1 out of 5 for Guiltiness would be the best, and a rating of 1 out of 5 for Overall Mood would be the worst.
