I think they are Greater Scaup. The bird in the second picture looks like it has a peaked crown, but Lesser Scaup should have the peak further back. And the two birds in the top picture have fairly rounded heads.

That looks good for Lesser Scaup with the more abrupt peak further back on the head. You can also notice less black on the tip of the bill.
