The rightmost would survive. The first two will probably die from the impact, but the next two will be entering the driver's cabin because the first two shattered the glass; they won't survive if the train goes full speed, though, and will go splat against the wall (and the conductor). The last two will survive with broken bones and injuries because the previous two bodies serves as cushion for them.
I wonder if it isn't a reference to a movie I tried to watch, 自殺サークル. I think the translated name is Suicide Club, and if I remember right, it starts like that. But with a lot more girls. Around fifty. And unlike what Rathurue said, there are no survivors in the movie.

If the train is going at full speed, can the conductor also die if he got hit by their bodies?
