Answer 1

Something like this should do it (may need some tweaks - haven't tested):

private static async Task WaitForAnyNonFaultedTaskAsync(IEnumerable tasks)
{
    IList customTasks = tasks.ToList();
    Task completedTask;
    do
    {
        completedTask = await Task.WhenAny(customTasks);
        customTasks.Remove(completedTask);
    } while (completedTask.IsFaulted && customTasks.Count > 0);

    return completedTask.IsFaulted?null:completedTask;
}
