Thanks alot guys, I know its alot of plants :)

The last one is Caesalpinia pulcherrima.

The yellow one might be a poinciana; having been to the islands twice in the last few years I purchased Flowers of the Caribbean. From page 51, "Dwarf Poinciana, Peacock Flower, Pride of Barbados. This small tree attains a maximum height of about 12 feet and flowers throughout most of the year. The flowers arise in clusters from the tips of the branches and although red is the common floral color, a yellow variety is also found". The foliage looks just like your picture. I have a red one in a pot on my front porch (but it certainly isn't 12 feet tall!)

No 2 could be a jacaranda going by the foliage, or it could be a royal poinciana. You won't know until it blooms.
Agree the last one is a dwarf pink poinciana and the yellow flowering one is a dwarf yellow poinciana.
The first one might be a variety of Calliandra.
