Akiko has a few friends in France.
Literal
Akiko [topic-は] France [in-に] several-people [possessive-の] friend [subject-が] exist.
A double-subject construction: 明子は (topic) + 友達がいる (subject + verb). Japanese often uses two 'subjects' this way — the は-marked element is the topic, the が-marked element is the grammatical subject of the existence verb. The に marks the location of existence. 何人か = 'several / a few people,' using the か-indefinite form.
