As the person above me has already mentioned, Martinique has a new official flag now that has been adopted since 2 Feb 2023. It consists of a red triangle at the hoist with two horizontal bands: the upper green and the lower black. The color scheme kind of reminds me of Libyan national flag.
Redonda, Adjara, and Lord Howe Island are not dependencies. Redonda is an uninhabited island that is a part of Antigua and Barbuda, Adjara is a political-administrative region of Georgia, and Lord Howe Island is part of Australian state of New South Wales.
Reunion doesn't have a separate official flag. They mostly go with the national flag of France. There are several unofficial flags though. The most common ones are Lö Mahavéli flag and the Regional Council of Réunion flag.
