How many unnamed Sherpas are there on the Adventure Consultants team and the Mountain Madness team?

I see no evidence in the text that tells us the number of Sherpas, named or unnamed.

Situated at the entrance to a magnificent natural amphitheater formed by Everest and its two sister peaks, Lhotse and Nuptse, was a small city of tents sheltering 240 climbers and Sherpas from 14 expeditions, all of it sprawled across a bend in the Khumbu Glacier.

Hall's Team:

There were fifteen of us in Hall's team: guides Hall, Harris, and Mike Groom, an Australian with impressive Himalayan experience; Sherpas, Ang Dorje, Lhakpa Chhiri, Nawang Norbu, and Kami; and clients Hansen, Namba, Beck Weathers, Stuart Hutchinson (a Canadian doctor), John Taske (an Australian doctor), Lou Kasischke (a lawyer from Michigan), Frank Fischbeck (a publisher from Hong Kong), and me.

Scott Fischer's Team

Scott Fischer's group—guides Fischer, Boukreev, and Neal Beidleman; five Sherpas; and clients Charlotte Fox, Tim Madsen, Klev Schoening, Sandy Hill, Lene Gammelgaard, and Martin Adams—left the South Col at midnight.

Makalu Gau's team

And then there was the Taiwanese team. Shortly after Fischer set out, Makalu Gau started up with three Sherpas, ignoring his promise that no Taiwanese would make a summit attempt on May 10. Thankfully, the South Africans had failed to make it to Camp Four and were nowhere in sight.
