April is the healer, she heals my team (obviously) and does some support by blocking abilities, delaying an enemy's turn, and dispelling buffs they have

Rahzar is the tank, he taunts the enemies to tank big attacks, while also very likely (75% chance) inflicting damage over time for 4 turns, which is the cooldown of that ability

Bradford is the support of the team, he buffs my team's attack and defense greatly, while also likely giving at least one team member counter attack

Stockman and Mutagen Man are the damage dealers, dealing a ton of damage to all enemies, while also having an attack that deals heavy damage to a single target
