No, you can't.

South Africa

Yes! I always bring biltong and droe wors back from SA to Israel (even in my hand luggage) and have never had a problem. Make sure the biltong is vaccum-packed.

Usually Chicken or Beef. Sometimes Lamb or pork.

We also have some traditional meats eg biltong (dried meat) or boerewors (a type of sausage)

South Africans love to "braai" (Barbeque)

No biltong is not bad for you and in fact it makes you eat less. This is pure protein that you are eating, meaning it keeps you full and keeps you away from those snack times
