Cost to expect for route in the Kathmandu valley, and North India...

I don't think the purpose is provide such a detailed description of costs for everything. Clearly, LP doesn't provide this forum so that users do not buy their guidebooks. Rather, I woyld expect forum is to add to the information in their guides. That is, read the guides, then ask.

Then may I ask a list of working cash machines (with Cirrus/Maestro/Interac logos) in the Kathmandu's valley, or do I need to generate a new question in the forum with this query in the title ?

Asking for a "list" of working ATM machines in the Kathmandu valley is both excessive and impractical (working today doesn't mean working tomorrow). Certainly easy to find in tourist areas such as Thamel.

However, ATMs that display the Maestro/Cirrus (never seen Canadian "Interac" logo in Nepal, but that didn't matter) are ubiquitous in the Kathmandu valley and Pokhara (even seen them in small villages, provided they were on roads). You will have no problem finding an ATM (bank ATM, not a private non-bank machine).

But take note of my warning about bring two cards. One likely be fine, but....

Hmm, I currently have two canadian cards : Bank of Montreal, and Caisses Populaires Desjardins. I'll ask them for information about cash machines in Nepal/India. Thanks for the info.

Almost certainly they won't really know.

We use a BC credit union card - - worked most times (but one trip not... in that case, we used our Bank of Montreal card).

WAY back in 2002, our only trip to India, our debit cards worked fine in India.

Are there any swindle to know about with the ATM in the Kathmandou's valley and Varanasi ?

Any problem like an ATM extracting money from your account but not deliver the money ? Or a machine that eats your card for no reason ? Or failed communication with Canada ?

WE never had any such problems.

Many years ago, a friend had their card eaten at ATM in Jomsom (at the time, a notoriusly inconsistent ATM), and it took some work in Pokhara (or Jomsom?) to deal with it - - all worked out, except for destroyed card.

Bank ATMs such as NABIL bank in Nepal have worked well. Be sure to use a machine that is clearly a banks (though they are very often not physically next to the bank). Usually inside a booth; sometimes with security guard outside of booth.

No idea/memory about Varanasi ATMs.

You can get a decent, clean room from 1000 to 1500 rps in Kathmandu, think twice before spending more than 2000 rps on a room.
Meals start at 200 rps in Thamel, even 100 rps in some other areas.

Thankful to @landfall38 for taking over babysitting chores.

Looks more like pa-troll duty to me. :)
