Does Koa'ki Meiru Maximus target?!
Maximus activates its effect to destroy monsters.
Yes. Older text saying "select" indicates targeting.
Can Call of the Haunted Special Summon Koa'ki Meiru Maximus?!
Koa'ki Meiru Maximus is in the GY and Call of the Haunted is activated.
Only if Maximus was properly Special Summoned first. It is a semi-Nomi monster and cannot be revived otherwise.

● The Ⓜ in this card's text is a maintenance cost. It is not an effect, does not activate, and can't be negated.
● As long as this card was initially Special Summoned by its own procedure (and the summon wasn't negated),
you can Summon it from the GY with card effects.
