The sky, and heaven with it. 天国 is paradise; 天気 is the weather.
A bud just breaking. 発芽 is germination; 芽生える is what a feeling does at the start.
Jasmine, in 茉莉花. Chosen for names almost entirely for how it looks and sounds.
The sky, and also empty. Buddhism uses the same character for emptiness — 空, śūnyatā.
