I have been using Kanger T2, T3, T3s for a while, and still love my T2 for best flavor and vape. I've also added a ProTank bottom coil and it's great. But my T2 is still always at the ready.
It's just getting harder to find the top
coils for the T2. Recently got my daughter set up and tried the Vision top coils (CE5... but I don't know all the model differences) and also ordered a SmokTech VT top coil system VERY similar to the T2 and I love it. Ordered another SmokTech for myself, too, rather than another T2 because of availability.
Anyway...
That shorter top coil looks like the Vision. I can say with a bit of certainty it shouldn't fit in a Kanger T2.
and one company said this pic is a T2 coil head

Yes. That looks like a T2 and it would likely fit. Difficult to say with certainty because of some "knock offs" or replacements that may not actually be from Kanger. The easiest thing to do is compare to the coil you're replacing. If that is not available, then try out the longer coil replacement in the bottom picture to see if it fits/works in your T2.
Hope that helps. Sorry. No pictures of mine available, but I ordered my T2 coil replacements here:

ETA: After finding the picture on line of the T2 heads I use, it's evident that the fitting on the bottom of these is different from the fitting on the pictures you posted. Not sure what those you posted are intended for. Probably won't fit if your tank is a true Kanger T2.
Try the LitecigUSA link above for the correct coils for the T2. They work perfectly in mine.
