I think it's really tough to get the light balance right early and late so you have done well in the first two, exposure slightly better in the second. Horizons in #2 and #3 both lean downwards to the left.
#5 is just over exposed in the top half and is a perfect candidate for using an ND grad filter.
Three is my favourite as the wet beach is painted by the warm sunlight where the waves have been on it.
