I want to do this:

I want to create a new list with names of another list. Eeach sublist from

Dear all,
What test should be done on ~40 samples (matrixes of 400x1), each in
triplicate, to determine which sample is the most different to all samples?
and What test should be done to determine the two samples which are most
different?

Dear all,
Novice in statistics.
I have 2 experimental conditions. Each condition has ~400 points as its
response. Each condition is done in 4 repereats (so I have 2 x 400 x 4
points).
I want to compare the means of two conditions and test whether they are same
or not. Which test should I use?
Dear all,
I am novice in statistics.
I have two matrices (results from my experiments), each having ~400 point. I
want to test whether the points come from a same distribution or not.
Further, I have the results for each matrix (each experiment) in 4
replicates. What should I do?

I perform an action on both mat1 and mat2, and I get
