They're showing an example of timed missile swarm attack with missiles calculated to arrive at the same time from different direction.
That second missile is hard to id but looks like the frame rate isn't quite fast enough to capture the entire missile. It looks like just the forward section of a staged vehicle is being powered by terminal boost but it's probably the frame rate/ refresh rate. Tip is definitely not the YJ-18's or the YJ-12's.
