Let's start from 1970s as I firmly believe the quality of cricket got better from 1970 onwards.
1970s/80s-Viv Richards, Greg Chappell, Sunil Gavaskar, Javed Miandad, Allan Border
1990s/2000s- Sachin Tendulkar, Brian Lara, Ricky Ponting, Jacques Kallis, Rahul Dravid, Kumar Sangakkara
2010s onwards- Steven Smith, Virat Kohli, AB de Villiers
14 names it is. Barry Richards can also be considered. So, 15 total.
Bradman, Sobers, Hobbs, Hammond, Hutton
