What HD are you looking to get?
The two (you have two?) Superdishes could be aimed at stronger FTA satellites for some reception through their FSS LNBs.
Regular LO of 10750 , so no surprises there.
We have threads to explain the bandstacked LNBs, when you are ready for those details.
The DP34 could even be used to connect them together, and feed several receivers, but if you want to do that, we should point you to a DP34 thread for more info , first.
It's a good part, but it's Dish Network hardware, and using it for FTA is somewhat restrictive.
That last dish sounds like a DirecTV Phase III dish.
You could maybe use it as is to receive NASA and Angel One from the Dish 119 bird, but that would be best discussed in its own thread.
Luckily, we do have one!

Or, outfitted with a linear LNB, it could be used to receive Whitesprings on 129 west.
Much of what you ask about, and answers relative to using Dish & DirecTV dishes, is answered in this recent thread:

Pay particular attention to the links given in the thread.
They provide much additional info.
Bottom line?
You're trying to use the wrong equipment.
It's not what I'd recommend, especially for a newbie (see thread above).
And so, explaining all the work-arounds to using "the wrong stuff" makes for a very long-winded answer.
edit: and unless I'm mistaken, those dishes won't get you a good enough signal to get the very limited HD that's on Ku-band.
Your first questions should be: "
what's on Ku band in hi def , and how user friendly are the receivers that get it?"
We have plenty of reading material to give you that background.
