#9: you are correct that Pokhara (and Annapurna region) are within Nepal's "Western Development Region". (Farther West are the "mid-west" and "far-west" development regions.)
However, for tourism/trekking purposes, "West Nepal" typically refers to areas west of the Annapurnas. See, for example, the Lonely Planet Trekking in the Nepal Himalaya guidebook.
I was just letting OP know where Chandrakot and Naudanda were located, as they seemed to be asking about places further West.
