Answer 1

You have at least two options for this

First. if you are using Code First, you can create Your Activity class together with the ApplicationUser class. see how here https://go.microsoft.com/fwlink/?LinkID=317594

Second. You can retrieve the user id just the way you did it here

result = await UserManager.AddToRolesAsync(user.Id, model.RoleName);
var currentId = user.Id;

Also your Activity insert has to come after the user has been created just as the code below

public async Task<ActionResult> Register(RegisterViewModel model, RoleViewModel role)
{
   if (ModelState.IsValid)
   {
       ApplicationDbContext entities = new ApplicationDbContext();
       var user = new ApplicationUser {UserName = model.UserName};            

       var result = await UserManager.CreateAsync(user, model.Password);
       if (result.Succeeded )
       {
           Activity activity = new Activity
           {
               RoleId = model.RoleName,
               UserId = user.Id,
           };
           entities.activities.Add(activity);
           entities.SaveChanges();
           result = await UserManager.AddToRolesAsync(user.Id, model.RoleName);

           await SignInManager.SignInAsync(user, isPersistent:false, rememberBrowser:false);

           return RedirectToAction("Index", "Home");
       }

       AddErrors(result);
   }
}

You instantiate the ApplicationDbContext context but you don't use it. You then use entities but where does that come from? With only the controller code shown here, my guess is you should do:

context.activities.Add(activity);
context.SaveChanges();

Finally, you pass in RoleViewModel role but you don't use it. Maybe you can remove that?
