• are several A, B, C, D, NG(E) and F
•The gripen NG was the version developed for the Brazilian air force, it is the most modern and because it was the most modern, it was called NG, but yes, the NG and E version are the same
•Yes, all flus are STOL

Because of the FX-2 project and because I am a Brazilian passionate about aviation, I know a lot about this plane.

1. There's 7 variants so far, A, B, C, D, NG, E, F
2. Unsure but I think the NG is a technology demonstrator while the E is a more finalized version of the NG
3. Yes, it only needed 500 meters of runway to takeoff and 600 meters to land, 400 and 500 with the older A and B models
