The second guy looks like a classic Ambanja. The first guy is definitely not an Ambanja or an Ambilobe. Assuming he is a pure locale, he is an east coast locale and I would say most likely Maroantsetra based on the red and white head and belly and then greenish on the dorsal portion of the flanks. Unfortunately, without lineage information on all blood inputs from when they were imported, its impossible to tell you for sure if it is a pure locale or not so he may only be partially Maroantsetra. Definitely not a pure Ambilobe or Ambanja though and even if he's a hybrid, I would say mostly east coast/Maroantsetra.
