Translation:Aloha e Kaʻiulani.
If you grew up speaking Maori, I suspect you'd find learning Hawaiian to be easy. Polynesian languages are structured very, very differently from English. Learning your first Polynesian language entails unlearning a lot of assumptions you weren't even aware you were making, then constructing many new, unfamiliar categories.
Expect progress to be slow, but worth it. Languages are tightly intertwined with their cultures. You can't really learn a culture without learning the language.
Those small words with 1, 2, and 3 letters often have many meanings and uses. The two words e in that sentence have different uses and meanings. The first one that is capitalized preceded the verb and makes it a command - "Speak!" The second word e before the name shows that the person is talking directly to Kawika and is addressing Kawika by name. "Speak, Kawika!" These two words have no direct translation into English, but they are needed in those situations.
