It would be pronounced like "dee fahn lowss", where faan rhymes with "John" and los "dose". You can see more detailed explanations on pronunciation here:

Note that the dragon language doesn't have an equivalent to the letter "C." "K" or "S" would be used instead, so "Cristi" should be spelled like "Kristi."

Dee fa-an los, I think

That's true.

paarthurnax,I am the guy that posted this question. I nt alphabet page how do I know which way I need to pronounce stuff? Like,how do I realize on my own that "Dii" is pronounced like "Dee"?

@Minkse, each letter has example English words that sound like it. You can also listen to the audio pronunciation provided. The special symbols next to each letter are part of the International Phonetic Alphabet. It's more technical, but if you can learn it, gives you a more precise explanation.
