こんにちは, long time lurker in this sub and now I’m finally able to post here, so I wanna ask something

If you don't know these characters, are you able to tell their names in kanji alone? I know I'm jumping the gun here, because I'm still very early in learning the language, but everytime I see these names, I'm intrigued at what's the logic to read their names, because I can't see the relation with their romanized names
