Well... two fingers and a thumb!
Hahaha yeah, I've noticed that. I wonder if it's better to have five or three fingers. I don't know, but somehow five fingers just says more possibilities. And more sock puppets
The Geth have three because they were built in the image of the quarians, a sort of "God created man in his image" scenario.
Only the Hanar truly differ from everyone else... being squid-like jellyfish and all.

They have lots of dangling fingers...
