Assuming you're both referring to the events of 19 March, they did not eject from the F-35. I know of no event during this war where an F-35 crew ejected.

It can, that's part of why these newer planes cost billions of dollars per unit. Assuming the plane is still controllable though. Usually in that case you wouldn't eject, but its technically possible. There was a case where a US pilot ejected on accident and their plane landed itself.
