Avian has about 10 total. One is his childhood team he released and later recaught, the other 4 are his macro cosmos provided raihan-at-home substitute team.

Stahl has an Appletun that evolved from an Applin that Arryn gave him. He has a collection of other pokemon under care at Macro Cosmos that I should put a little more thought into🤔

Arryn has a Fidough and Lechonk she's travelling around Paldea with outside of his main party.
