You want a view model that holds all the data you want to insert, then in your controller create the objects based on that view model and insert using EF. Something like:

public class MyViewModel
{
    public string Name {get; set;}
    public string Birthday {get; set;}
    public string VerNumber { get; set;}
    public string Email {get; set;}
    public string Address {get; set;}
    // etc etc for the rest of your data
}

Then in your controller, use your ViewModel to populate your entities, then insert using EF:

[HttpPost]
public ActionResult Add(MyViewModel model)
{
     var client = new Client{
          Name = model.Name,
          Birthday = model.Birthday
     };

     var clientDetails = new ClientDetails();

     //etc for your other entities

     using (var context = new MyDbContext)
     {
          context.Clients.Add(client);
          clientDetails.ClientId = client.Id;
          context.ClientDetails.Add(clientDetails);
          //etc add your other classes
          context.SaveChanges();

     }

     //whatever you want to do here for the result, maybe direct to new controller
     //or return view
     return View();

}

You may want to look at tidying up the entity framework code using a Repository Pattern and you could also look at automapper to map entities from your viewmodel, to save doing it manually.
