Being a Faux-Hybrid direct to battery connection mod you'll need the atomizer/tank center positive pin to stick out at least 1/16th to 1/8th inch from the outer negative threads, also good to look at is the bottom positive pin insulator of the atomizer/tank is not a silicone or rubber insulator, but a hard insulator like delrin (generally a white or black plastic) or PEAK (generally an off white or tannish cream color plastic that has higher heat resistance than delrin).
Now, looking at what RDA's you've posted up and how fuzzy most are in the picture, I can only give a guess as listed below
#1 Definite no, the pin is to flush with the threads
#2 Same as #1
#3 Same as #1
#4 Same as #1
#5 Same as #1
#6 Is questionable, I can't see if that is a pin or the threads clearly being to fuzzy
#7 Same as #6
#8 Yes, can clearly see that pin is protruding enough to keep the RDA negative threads away from the battery positive top cap
#9 Same as #8
