Picture 1. Blue ones are cobalt, spotted at front is a leopard and spotted at back is leopard snakeskin. The little red one in the reflection is a red cover.
Picture 2. Red melon (pigeon blood) in middle and blue diamond bottom left.
Difference between blue diamond and cobalt is that a blue diamond has no black bars.
Different between a spotted leopard and leopard snakeskin is that a leopard snakeskin has 14 bars rather than 9 and this makes the spots smaller. Your leopard snakeskin looks like it has golden genes, so the bars are not visible (therefore called golden leopard snakeskin). Leopard snakeskin is sometimes called eruption.
