I have played at 81Dojo for a few weeks and got a sense of how each dan means here. 
I would say "Nimai-ochi" (no bishop and rook) would be appropriate for a wide range of players, say anyone from 2-dan to 2-kyu. I recommend "Nimai-ochi" for most people because "Nimai-ochi" is the most popular handicap, its "jyoseki" is well developed, and it is easy to find a textbook for that.

It depends on every person level, but for a 1-dan should be a handicap of bishop and rook.
