This Reinhardt used by the team in clearing the map chipped Freyja's HP down with Savage Blow 3 and Blazing Thunder.
Freyja starts with her Special already active, so she could one-shot your unit if she is allowed to counterattack.
She can also counterattack regardless of range, so attacking her when she is full health with a ranged unit is also dangerous.
The best way to defeat her on this map is to attack her allies with skills that do AoE damage like Savage Blow 3 and a Special like Blazing Thunder.
This will bring her HP down enough that she could be brought down without any worries.
However, Freyja does get stronger when she is alone, which could make taking her out when she's alone very tough.
Try leaving one enemy unit with her and defeat her first. Or use units that have Dazzling Staff 3 or Flash+ so Freyja cannot counterattack.

In addition to her status as a green beast, Freyja is considered a cavalry unit.
This means that weapons that are effective against beasts or cavalry will be able to take her down, though keep in mind that Freyja will be able to reduce damage from units with lower speed than her.
A good unit that can potentially take Freyja out in one turn is Brave Lysithea.

Triandra is the other boss and is a dancer.
She will inflict debuffs on your team when she uses Frightful Dream, which is troublesome to deal with, so aim to defeat her first before dealing with Freyja.
She also possess Iote’s Shield, which will render flier-effective weapons ineffective, so take care in picking your team.

There are several enemy units that could debuff your team, like Triandra's Frightful Dream, so using units that neutralize debuffs are very helpful.
Because the map contains several reinforcements, it's important to defeat them as soon as they spawn.
Using dancers or skills that grant another action like Galeforce, or skills that grant mobility like Armor March 3 could prove useful in defeating multiple enemy units at once.
