The white one is a XEV Yoyo: https://en.wikipedia.org/wiki/XEV_Yoyo which is an EV from Hong Kong. It's one of the few EVs with a swappable battery pack.

The gray one is a Citroën Ami: https://en.wikipedia.org/wiki/Citro%C3%ABn_Ami_%28electric_vehicle%29. It's a Quadricycle which means the driver doesn't need a license to drive a car.

The little red car is a Smart Roadster Brabus: https://en.wikipedia.org/wiki/Smart_Roadster.

I had to look up the Smart and the Citroën . I read about the Yoyo a couple of years ago since I've been researching EVs since I'm considering one as my winter vehicle when my Corolla finally dies.
