Considering that Guatemalan, Russian and Belarus athletes are neutral, therefore not representing a NOC, it does feasible for me to think that their quotas will go to IOC/"Neutral Athletes" Team or something on that regard.
What I'm still struggling to understand is if Russian and Belarus will count as "one team" in the matters of quota. In Tennis rankings for instance (could 6 russians and 6 belarussians go or 6 in total? could russia and belarus form a pair?).
But in the meantime, their quotas are secured, as it's fair to be, since the athletes won (if they are allowed or not to participate is another matter, but since they are, they should be able to earn their quotas).
