Russian anti-tank missiles

I’m having some trouble figuring out the various launcher configurations for the newer Russian ATGM’s. Some help would be appreciated.

I’m seeing eight and six-round launchers. The six-round stuff I’ve seen on the Ka-50 is the AT-16 Scallion? (Please bear with me and use the NATO designations….the various 9Mxxx type designations just confused me even more)

The eight-round launchers I’ve seen on the upgraded Su-25’s and the Mi-28 is the AT-9 Spiral-2 or the AT-16?

Do the AT-9 and AT-16 both come in 8 and 6-round launchers?

(Oh, and to clarify….the older AT-6 Spiral comes in four-round launchers?)
