They all sound fantastic tapao.
"white russian (white widow x ak 47)."
Gonna smell like a dead skunk after a cat pissed on it. A sick cat with a bladder infection. Be sure to have odor control.
An alternative could be Double Dipped Sour Banana by Elite.

"king kush (grape ape x og kush), "
Don't know anything about this cross, two fantastic parents. If I wanted a purple or grape strain I'd get Querkle from Subcool - reviewed as the one purple/blue strain most likely to take the top of your head off. Consistent taste, where some strains have little fruit taste.

"jack flash"
I've got a Jack Flash #5 seed from Sensi. I really don't know how do advise on this: Jack Flash has the Jack Herer phenos down to 2 from 4 but I haven't read too many reviews on Jack Flash. Those I have read have been positive.
#5 or regular ??? ... I've got the #5 but I've had trouble with other fem seeds and sexual stability (hermie). Not a lot of complaints about Sensi around the net, solid breeder.
-- As an alternative you could look at Kali Mist by Serious Seeds or Super Silver Haze. Kali will be more of a floaty high than the Jack Herer trippy; SSH reverses the sex of the parents on the last cross.

"cheesus (god bud x cheese)"
I know nothing about the strain but how can you go wrong with those two parents.
An alternative might be a Cheese S1 from the original clone.
