As for the other two, I thought maybe they are both Pterostichus species, the second one perhaps P. niger, but I've still got 1hr 15mins of the YouTube video to watch, so if you've a better idea, please let me know! (Pictured here again)

Edit: now confirmed as Nebria brevicollis and Pterostichus niger.

3/3
