It is very important that puppies are socialised with people during the first 3 months of their lives. This helps them cope better with living in a human world later on in life. If they have not had much contact with humans getting them to be people dogs will be a lot harder.
A good approach is to not make a huge song and dance about it. Begin by dropping bits of food for them to pick up and calmly wander away. Then after a while sit down and place some food a bit closer and then once they are happy at this distance begin to hand feed them. Do not attempt too quickly to grab at them or try and stroke them. Don't worry if this takes weeks.
It might be a good idea to seek advice from your local recommended behaviourist to see if they can help a bit more. You will have to get them used to humans so they can have their vaccinations etc.
All the best
