In this blog I've collected all confirmed names of Amidala's handmaidens throughout the Saga. 'Secrets of Naboo' mentions that Amidala (and later perhaps the other Queens) has 13 Handmaidens at her disposal.

THE PHANTOM MENACE:

Eirtaé: Is the blonde handmaiden that accompanies Amidala to Coruscant. She can be recognised be easily. Eirtaé excels in etiquette and protocol and comes from a wealthy family on Naboo. Can detect betrayal. Actress: Friday 'Liz' Wilson (°1979)
Eirtaé

Padmé: Is of course Queen Amidala herself. Padmé is supposed to be a Royal messenger. Actress: Natalie Portman (°1981)

Rabé: Is the darkest of all handmaidens that accompany Amidala to Coruscant. She is young, but has patience. She helps the Queen with her hairstyle. Rabé is the handmaiden who says to Anakin that Padmé has gone away on Coruscant when he comes to say goodbye. Excels in the use of weapons and in forms of persuasion. Made by Hasbro as an action figure. Actress: Karol Cristina da Silva (°1975)
Rabé

Sabé: Is the decoy Queen that traded places with Amidala. Sabé was Amidala's best friend. Resembles Amidala the most and some have thought that they are sisters. Wears the 'black travel gown' and the 'battle dress' as decoy Queen. Has two Hasbro action figures. Actress: Keira Knightley (°1985)

Saché: There is not much known about Saché, except that she had to stay on Naboo. She is one of the younger handmaidens. Actress: Sofia Coppola (°1971)

Yané: There is not much known about Yané, except that she had to stay on Naboo and was the youngest of all handmaidens. Actress: Candice Orwell
