How to insert multiple fields at once in Entity Framework asp.net mvc5 database?

Question

ASP.NET

Essence of the question:
a web store is being developed, respectively, there is a Basket, in which goods from the Catalog are added. From the Basket, the goods are checked out and transferred to the Order History. The problem is that if more than one product was added to the Cart, then only the first added product will "pass" to the Order History, and the rest will be deleted.
I'm begging for help.

[HttpPost]
        public ActionResult Orders(HistoryOfOrder history ,Order order,Stuff stuff, int Id )
        {
            var user_name = this.User.Identity.Name;
            var find_user = db.Users.FirstOrDefault(u => u.login == user_name);
            var userId = find_user.Id;
            var query2 = 
                         from o in db.Orders
                         where o.UserName == user_name
                         select o;
            var query3 = from h in db.HistoryOfOrders
                         select h;
        

            

            foreach (var all_order in query2)
            {
                if (query2.Count() != 0 )
                {
                    HistoryOfOrder all_history1 = db.HistoryOfOrders.FirstOrDefault(p => history.Id == p.Id);
                    all_order.Adress = order.Adress;
                    all_history1.UserName = all_order.UserName;
                    history.Order_id = all_order.Id;
                    history.NameOfOrder = all_order.NameOfOrder;
                    history.Image = all_order.Image;
                    history.Price = all_order.Price;
                    history.Quantity = all_order.Quantity;
                    history.Summ = all_order.Summ;
                    history.Size = all_order.Size;
                    history.Adress = all_order.Adress;
                    history.OrderTime = System.DateTime.Now;
                    history.Status = "не оформлено";
                    db.Orders.RemoveRange(all_order);
                    db.HistoryOfOrders.Add(history);
                }
                    
            }
           
            db.SaveChanges();
            return RedirectToAction("Orders");
        }
