You compare the number of lands you control with the number of lands each opponent controls as Beza's ability resolves. At that time, if at least one opponent controls more lands than you, you'll create a Treasure token. Similarly, you compare life totals, creatures controlled, and cards in hand with each opponent as Beza's ability resolves. If at least one opponent has more life, creatures, or cards in hand than you, you'll get the appropriate bonus. It doesn't matter if you qualified for any of the previous bonuses or not.
