what do you mean by pack of one and where this made from.

It means 1 spark plug each. Denso products are made either in Japan, Indonesia or China. I replaced all 4 of my plugs with this brand over two years ago and so far no need for replacement. They have now been on for over 100K miles working flawlessly.

where are these made?

Had purchased few years ago and to the best of my knowledge, these plugs were made in Japan.

does it fit a nissan quest 2011 s model?

This is what you and all that have a "fit" question do. Go to "DENSOTT.COM" then "Find Your TT Plug". You will have the correct answer and not rely on other "experts". It's a great pug at a good price.

Spark plug socket size needed?

9/16 or 14mm six point deep socket. Preferably with rubber insert to hold plug in, but will work without.
