I've never dealt with Dish Network (Only Directv, Frontier, Spectrum) and trying get a bid together.
So customer has it and also gets some type of "foreign" channel(s). The questions are:
How many RG6QS are needed to the dish and each TV (receiver) location? We use Ice Cable bare copper RG6, which I assume will great cable quality.

I have not installed any, but I do have Dish at my house.  We have a single RG6 feeding from the dish, and one RG6 to each box through a splitter.

What Mike said

Cool, we usually run two RG6 to each TV location and three to the sat location,just to be safe. So, sounds like we'll be covered!!

Don't forget that Dish allows the Hopper 3 and Joey's to be connected via CAT5/6/7 as well as wifi. Though I am not sure about 4k via wifi.

I currently have the Hopper 3 connected to the dish via coax, obviously. Then to wifi for the on demand and such. But I also have a traditional Joey 2 (not specially made wireless from Dish). Connected to the wifi via a Dish suppled dongle. All this using two Apple AirPort Extremes.

So far I haven't heard any complaints from the Joey user and it's been a year.

It does work via CAT5/6/7 as well, I just don't have it hooked up like that in this house.

For the satellites we run, we typically do two/four cables to the dish plus the ground/bond and two cables to each TV. Although now I believe most boxes can accept 1 cable with a splitter for the dual tuner if needed.

International may be a separate dish altogether with a combiner. You may need more than 1 RG6 to the dish location.

Get setup with the CI program with Dish. You sell the equipment, deal with the Concierge Team (way better and faster level of service), and make ROI on all accounts with more than 3 STB's.

I have never run more than one coax to a dish and its never not worked. Why more? If you have more than a certain amount of boxes or something? Then you go with some sort of MoIP solution. who needs more than 3 or 4 boxes?
