How do you say are you still there in Spanish?
You could say "¿Aún estás allí?"
A Spanish-speaker reading 'Kimberley' would pronounce it (roughly) KEEm-bair-lay-ee. If you wanted a Spanish-speaker to say it as in English, you could of course SAY it if you were both there in person. If communicating it in a letter, for example, the English pronunciation, written in Spanish, would be (roughly) 'kimbali' (but would still come out with a Spanish flavour).
