Please clarify it to me, you have data table of the size: 20 x 6, right?
And you want to see which one of those 6 are different or same, correct?
So if you have normal-(like) distribution, you can do any t-test (like method)
However, probably more interesting would be to see whether there are some correlations between those 6.
Maybe you could try some PCA as well
For the future reference: always say what is the size of your table, because not all the methods work with all the sizes.
