I've seen what you're talking about and I'm pretty sure it's the "naga." I'm not sure if there's any significance to the 5 headed ones you saw as there's several different kinds. It's a symbol all over SE Asia in different forms. It's a symbol of fertility and strength according to one of the web sites. I linked some information for you below.

The pathway leads to the raised cruciform naga bridge which has rails in the form of a five headed naga, a mythical snake. It is believed that this bridge links the human with the heavenly realm. In the middle of the bridge is an eight petalled lotus which could symbolise the deities in the eight directions of the Hindu belief. It could also mark the point where propitious ceremonies were performed or where pilgrims made vows before proceeding further.
At the end of the naga bridge are 52 steps leading to a plateau at the top of the hill. In front of the arched doorway in the eastern gallery is a second naga bridge. The gallery is a rectangular structure surrounding the tower on all four sides. It is not possible to walk through the gallery as it is blocked in sections by a wall. In the centre of each wall is an arched doorway, while the corners of the wall are cruciform. The external gable of the eastern wall carries a relief of Shiva, in the manifestation of a healer. This could represent Narendradit who constructed the complex.

It is the naga in Thailand. It symbolises the snake spreading its hood to shield Lord Buddha on a sunny day, hence its reverence and presence in the temples. The naga is treated with respect there. There are many folk lores associated with the naga, but I apologise, I could not remember.
