Catalysis of the transfer of a hexosyl group from one compound (donor) to another (acceptor). Catalysis of the reaction: UDP-N-acetyl-D-galactosamine + glycoprotein-alpha-L-fucosyl-(1,2)-D-galactose = UDP + glycoprotein-N-acetyl-alpha-D-galactosaminyl-(1,3)-(alpha-L-fucosyl-(1,2))-D-galactose. Catalysis of the transfer of a glycosyl group from a UDP-sugar to a small hydrophobic molecule. Catalysis of the transfer of an N-acetylgalactosaminyl residue from UDP-N-acetyl-galactosamine to an oligosaccharide.
