Kareem @6 for NBA? not even close to Bill Russell of the Celtics with 11 championship rings or a group of several others who have eight or more.
In 13 NBA seasons, Russell won 11 world championships, including eight straight from 1959-66, and played in the NBA Finals 12 times. Russell also won two college national championships at San Francisco. Teammate Sam Jones was on 10 of those 11 NBA Championship Celtics teams, missing only Russell’s rookie year in 1957. Their teammates Tom Heinsohn, K.C. Jones, Tom Sanders, and John Havlicek all have eight.
Robert Horry is the non-Celtics player with the most NBA Championships, with seven.
