Xanthippe- Greek, from 'xanthos' meaning yellow and 'hippos' meaning horse.
Yadira - Hebrew, meaning "friend".
Zenetta - One possibility is that this is related to the French Zanette, which comes from the Hebrew John meaning "God is gracious". On the other hand, if it is related to the Greek via Zanetta, then it would mean 'long teeth'.
Azucena- Spanish variant of an Arabic name meaning "lily". Pronounced "ah su say nah".
Braulio - Spanish, derived from German and means "shining".
Chilperic - From:

I found more than one possible origin for this name. Behind the Name suggests that it may come from the name of a knight featured in a medieval poem from Brittany, Sir Degare, which they think comes from the French word 'egare' meaning 'lost one'.
This is the same etymology (essentially) provided by Llewellyn's Book of Names, though they give more details. It is important to note that in their supposing where Sir Degare's name may have come from (they provide other spellings, but we'll stick to the one previously indicated) they suggest perhaps a connection to the Celtic name Dungarth, which belonged to a fabled king of Dumnonia. This they connect to the roots dubno, meaning 'deep' and 'world' and 'kar-o' meaning, 'to love'.
A new name blog I came across, just by researching this name, is firstandmiddlebabynames.wordpress.com. Clicking on the link will take you to the discussion Elizabeth McKeown hosts there, this one, specifically, on Diggory. She offers the meaning as 'astray' but following a similar derivation as Llewellyn and Behind the Name.
Babynamespedia, however, says the name is English and means 'from the dyke'.
