'Ko' means "child" in Japanese.
Ryu means dragon in Japanese and ko means child in Japanese
Apparently it means little or child in Japanese. That's why you see lots of female names ending with ko.
"child" common in female names
This does not appear to mean anything in Japanese.
The translation is "Ko" yes, Child in Japanese is "Ko"

mahal ko
If that's some sort of a name, the Japanization would be ニコレ /ni ko re/.
I think the phrase you're looking for is "nani kore?" which is "what's this?" in Japanese.
As a name it can be both ティコ /ti ko/ and less commonly チコ /chi ko/ (Japanese don't originally have 'ti' syllable, instead they use 'chi'). As the name of the impact crater on moon it is ティコクレーター /ti ko ku ree taa/ meaning 'Tycho crater) or in short just ティコ /ti ko/.[ee = elongated 'e' sound]
"Hana" is flower. "Ko" is little so "Kohana" means little flower but not sure about "Ka".
