just like jambudwip are there other areas like it ?
Yes. In Jain cosmology the world is described as divided into multiple dvipas (continents) around Mount Meru. Jambudvipa is the central, most inhabited continent, and there are six other dvipas that surround it. In total these are often referred to as the Sapta-dvipas (seven continents). The exact names of the other dvipas can vary a little between Digambar and Śvētāmbara texts, but they are all described as distinct landmasses in the Jain cosmological map.
If you’d like, I can give you the precise names as they appear in specific Jain scriptures (and note any differences between Digambara and Śvetāmbara interpretation) with brief, authentic meanings.
