It's not organized in a way that ranks the players, but it shows all players and what competitions they were in. You'll have to pick through the list to find your NBA players though.
btw, are you referring to players who have played in the Olympics as ONLY NBA players, or are you also counting college players who have later went to the NBA? Because in any case, the list of players with multiple Olympic appearances is quite short. Given the nature of the USA basketball program, the teams changed every Olympics fairly much. Only guys that really pop out in my mind who have played in multiple Olympics are David Robinson(88,92,96), plus a bunch of guys like Payton/Malone/barkely/etc who have each been in 2.
