What bond is more polar C-N or Br-S and which way does the dipole point?
The C-N bond is more polar than the Br-S bond based on differences in electronegativity values (∆EN). The dipole will have the negative pole at the N and the positive pole at the C. For Br-S, the negative pole is the Br and the positive pole is the S.

No. The Biuret test only gives a positive result if a peptide bond exists. Phenol doesn't have a peptide bond, so it will not give a positive test.
What do you do when subtracting a positive and a negative?
If you subtract a negative from a positive, add both of their absolute values. If you subtract a positive from a negative, add both of their absolute values and multiply by negative one.
