ID for two silvery angels?

These photos don't really do them justice, I'll be taking a few more tonight. When the angels are in their "home" (planted biotope) they seem to change colour depending on what's going on. Sometimes they hide their black entirely and just appear pale silvery grey. When they're begging for tea, they gain proper little bandit masks.

"Stumpy" (only fish I've ever named - if I get more pics you'll see why):


Other one:

The top 2 images look to be a Blue Koi (AKA Blushing Silver Gold Marble) Gm/+ -S/S.
The other angel in the bottom image looks to be a Silver +/+ or Silver Ghost S/+
Any way thats what they look like to me, be nice when they are back in condition

Thanks for the help! Though I'm not sure what those abbreviations mean.

Koi are patchy though, right? These guys (despite what the pictures show), are all one tone. The grey patches are due to some kind of reflection, to look at them in person they are one silvery/pearly shade. They have strange scales on their lower halves too, as though the scales are bigger and rounder.
I like that when they are in their home tank, their gill plates glow turqoise.

Stripey fish was rehomed last week due to being a terror.. It's just the only other clear photo I have of my silvery one. I hate when the most beautiful fish are the most violent.

I'm not sure what the first fish is, ghipsi is probably right with blue koi. If the second fishes stripes fade, it probably a ghost.
