All blacks who were used as slaves have died since the passing of the 14th amendment which ended slavery in the US. I assume you mean how many blacks died as a result of slavery. In that case, the number is around 4,000. Actual slave deaths were relatively low because they were very expensive and were only killed if they posed a threat to citizens or other slaves.
blacks died during slavery because, they didnt have much food or drinks and they was beaten when they get acuse of stealling...
Impossible to say. Slavery pre-dates written history

The blacks moved North to avoid slavery.
After slavery some blacks were already in Canada and the north, although some did stay in the south.
