I have 4 rainbow skillblooms and 4 rainbow dressblooms

I have just finished leveling up Fritilaria and Pumpkin to 80. Should i toss them both 1 of each and then use the rest on Loquat?

Kerria 3 skill / 3 dress
Dendro 3 skill / 3 dress
Sakura 3 skill / 2 dress
Alpina 3 skill / 2 dress
Ghost Weed 1 skill / 2 dress
Apricot 3 skill / 1 dress
Black Baccara 2 skill / 2 dress
Daisy 3 skill / 2 dress
Mei plumblossom 1 skill / 2 dress
Alstore Maria 2 skill / 1 dress

Now the rest of my 6 stars are at 1/1
including Anenome, Fritilaria, Pumpkin , Lotus, Both Heleniums, Hebaceous Peony, Horse Chestnut, Dogwood, Maple, Inocidium, Victoria

Should i max out Dendro and Kerria before i consider all my other girls? How would you use them?
