No, they're travelling in different directions more or less randomly, but with some tendency to move about the center of the cluster.
They're not all travelling in the direction of expansion of the universe, but in general, more of them will be heading away from each other than towards each other.
It is possible for two stars to hit each other as you describe, but incredible unlikely. The distance between stars is typically around a million to a billion times their diameter.
I assume you're talking about the Perseus double cluster from today:
