Answer 1

Assuming your entity is defined something like this:

 public class Order
 {
       public string product;
       public string quantity;
       public string cost;
  }

You can Zip to combine the lists and update the database:

 var orders = ListProductName.Zip(ListProductQuantity, (p, q) => new { Product = p, Quantity = q }).Zip(
            ListProductCost, (p, c) => new Order() { product = p.Product, quantity = p.Quantity, cost = c });


        db.Orders.InsertAllOnSubmit(orders);            
        db.SubmitChanges();
