Almost correct. You emphasized in the right syllable (Danylo), but you mispronounced the second vowel. The Google translator knows how to do it, although he can't cope with the emphasis. Overall it was a good attempt :D
The second one is actually correct. Most people go with the first one since I don't have an umlaut on the o, but the reason for that is simply because several sites I use this name on don't allow for umlauts in usernames.
Have a nice day!
