Fake Sprite Bottles: Which one's real?

We were eating at a roadside restaurant near Mohammad Ali road, the best place to get awesome kababs, meat rolls, etc. All of us ordered Sprite to drink because plain water, even bottled, could be a bit risky in that area. Five minutes into the meal, we notice that each bottle has a different font, with a different Sprite logo:

For those that didn't see it the first time, here's a more focussed look - notice the "p's" and the lemons. I love noticing this stuff, and freaking people out. lol.

I mean, if this isn't Sprite, what is it?

Looked on the net for the actual thing (as far as I can discern). Check out the main differences between the four found bottles, and the one below:

1. The lemon is squashed in the first two, is absolutely redrawn in the fourth

2. The "trademark.." text below the logo is absent in all four

3. The p is drawn differently in all of them.

Not at all surprising was the fact that it didn't taste different at all, whoever was making the stuff, and running their tiny business somewhere in Mumbai; at least made sure that it tasted pretty much the same.
