We have no idea on the full capabilities of the three so have no way to tell that.

Ajuka's ability is pretty powerful too. He can control any phenomena. That's the only thing we know about him and just that is powerful enough to him to be classified as a Super Devil.

In Rizevim's case, Sirzechs created his team with Rizevim's ability in mind. It can be Sirzechs just being overly cautious or he just respects Rizevim's power.
