For def up buffs (such as Lux Halcyon Atro), as long as two others (maybe let's say you put Atro with Mikael) do not have SAME DEF BUFF (will stack with boost def relative to atk, or any of that junk), the def up will stay the same. Just to clarify further for Killpuke, Mikael and Atro's Defense buffs would conflict, but Mikael's Defense Conversion Buff is a different type of buff, so it doesn't. Attack conversion is a different type of buff from Defense conversion, so they won't conflict. The stat that is being boosted by the conversion is what counts.

So an Attack=>Defense buff and a Defense=>Attack buff are fine, because one is boosting Defense and the other is boosting Attack, but Attack=>Defense and Recovery=>Defense won't stack because they're both boosting Defense, even though they're using a different stat to boost the Defense with. Attack Conversion, Attack, Defense, and Defense Conversion will all stack with one another, because these are four different buff types, in the same way that Spark Critical isn't the same thing as Spark Damage or Spark Vulnerability. :)
