Meanings

sisters; female siblings

Refers to one's sisters or female siblings collectively. Often used when specifying gender among siblings, e.g., in contrast to 男兄弟 (brothers).

男おとこ兄きょう弟だい
Refers to brothers or male siblings, the male counterpart of 女兄弟.
姉し妹まい
Also means 'sisters', but is more common and neutral; 女兄弟 explicitly emphasizes the female gender among siblings.

女おんな兄きょう弟だい
Standard kanji spelling for 'sisters' or 'female siblings'.
女おんな姉妹きょうだい
Rare variant spelling; 姉妹 alone already means 'sisters', so this form is redundant and seldom used.

Compound of 女 (onna, 'woman/female') + 兄弟 (kyōdai, 'siblings'). The reading きょうだい for 兄弟 is standard when referring to siblings in general.
