I guess it depends on their distance and such, since Ingrid can freeze city-wide areas and cause storms. But I can help but think that Cora and Regina could use mirror magic and snip- I mean fire blast them away.

They could simply appear in front of them and Zelena cast a sleep spell over them, like she did to the Merry Men, or they immobilize them and kill Elsa and Ingrid. Even if Emma is immune, it will be three against one.

Even if they start apart, Regina uses several spells, protection and natural barrier spells that would be defensible while Cora uses Mirror magic to locate them and Zelena sends a fireball thru killing them one by one.
