I tried to search for tutorials about this but I really couldn't find that much useful information. I kind of know how to do the actual turret but other than that I have no idea about this.
What I want to make is an automatic shooting turret that switches targets, it is going on a deathrun map. I would like the turret to start automatically shooting each round and keep shooting at all times, it would have 5-6 targets that it switches between so that the CT have to learn the pattern to avoid getting shot. I could alternatively make a turret that automatically shoots and follows a target if thats possible.
I made a small screenshot trying to explain what I'm trying to do:

Any ideas and detailed help would be appreciated.
