You need 6 hoses to do a recirc chill with a therminator (or other plate chiller). Three for the wort side, three for the water side.
Add a Hop Rocket and you need at least one more hose on the wort side yielding a total of 7.
I have 7 hoses now but the one not mentioned is the discharge hose for when I use hose water to do the chill down (i.e. don't recirc ice water).
My males and females are mixed depending upon the application. All of the hoses have the males on the ends, it really depends on your thermocouple arrangements.
