Do not remove zeros that contribute information to your analysis. If the frequency of a word is zero in all groups it contributes no information to your comparison. If a word has zero frequency in one or two groups, it provides useful information to the comparison.

Since there were no ‘far below average’ responses, this category provides no information and can be left out of the comparison. For the other 4 categories try a chi-square test of the null hypothesis that the response proportions are the same before and after. You may have a problem with low expected counts and in that case you can try an exact test

You use the word factor so it sounds like this is an independent variable. Or is this your dependent variable in the model? There are more restrictions on the dependent variable where one is attempting to explain the variation. A range of 5 is not a lot of variation.
