Most any of those glues will stick to dry, clean balsa. You could do a test. Model airplanes are glued together using all those glues. Stones, metals, and plastics are best sanded and left clean for a good epoxy bond. Dry clean balsa will bond easily to all mentioned glues. I use 330 on stones to acrylic. Both surfaces are best left rough, especially the acrylic. It does not bond well.
