I can't speak for the building practices of the Bahamas since I learned what I know in jolly old England. But here's the skinny:
First, is it a partition wall or a foundation wall?
If it's the former you'll need some plasterboard to replace the damaged wall sections, some drywall screws to secure the boards into position on the joists, some multi-finish to plaster over the wall and some decorating bits for painting and finishing afterwards.
If it's a foundation, then you'll need to hack away all the damaged wall sections and concrete any damage to the internal brickwork. After that you'll need some drywall adhesive to secure the new boards to the brickwork (you can use screws with rawl plugs, but they'll be more likely to break under pressure) Finally you'll need some skrim bandage on the edges before plastering.
It can be done with DIY, but your area may have building regulations that need to be adhered to.
I'd advise checking material prices and getting an estimate from a local reputable contractor. Shouldn't be more than one to one and a half days work.
