AH stands for Acidic Helix.  This comes from an experiment in which
random E. coli DNA was fused to the DNA binding domain of Gal4 to
help figure out what sorts of sequences can activate transcription.
In the experiment they found that an acidic amphipathic helix could
activate.  I'm not sure if the AH is actually one of those E.coli
derived sequences or an artificial construct based on them.
GAL4-VP16 is a fusion of Gal4 and the bipartate activation domain
of the VP-16 protein.  VP-16 stands for Viral Protein-16, a very
descriptive name.
