8 teams from each conference. The top teams from each division (makes up 6 teams) plus the next 5 best records of the according conference, so even if the 8th best team in the eastern conference has a better record then the 9th best team in the western conference the latter will not advance.

That depends on how many games the other playoff contenders have won.
Each team that qualifies for the NBA Playoffs must submit a list of its players eligible to compete in playoff games on the day following the end of the regular season. Because there is no Injured List for the NBA Playoffs, each playoff team must designate the 12 players eligible for the playoffs from all of its regular season lists (Active, Injured and Suspended). A player who is on the Injured, Active or Suspended List at the end of the regular season, but who is not designated for playoff eligibility, need not be waived. He remains on the appropriate regular season list through the NBA Playoffs. Teams must have at least nine eligible players dressed and able to play in a playoff game. Teams failing to comply are subject to fines.
Each team plays 82 games in a regular season. They play 41 games at home and 41 games away. The amount of games may vary if the team makes it to the playoffs. In order to win an NBA championship, the team must win 16 games, whether it be all at home or away.
