Answer 1

You could implement IValidatableObject Interface

Something like this:

public class MyObject : IValidatableObject
{
     public IList<AccountAddress> BulkOrderAddresses { get; set; }

     public IEnumerable<ValidationResult> Validate(ValidationContext validationContext)
     {
          if(BulkOrderAddresses == null && !BulkOrderAddresses.Length > 2)
          {
               yield return new ValidationResult("List should contain more than 2 items");
          }
     }
}
