Answer 1

You need get user user information from user manager:

string username = HttpContext.Current.GetOwinContext()
    .GetUserManager<ApplicationUserManager>().FindById(ID).UserName;

you can get the username of any MembershipUser using the below code:

string userName = Membership.GetUser(userId).UserName;

userId is the Guid primary key of the user.
