1- When, exactly? Because none of the world class board game players were affected when the King summoned them. They were just terrified. It probably was that Pitou's aura filled the whole area and it was probably the natural feeling around the palace if you spend some time around there.

Gon and Killua couldn't step into a hallway filled with Hisoka's Aura because they felt a murderous intention, it's factible that Pitou's intentions weren't murderous all the time, like, for example, when he is relaxed or doing nothing.

2- It's highly likely Netero was covered only to a very minimal extent, like Biscuit explains, you can distribute your Aura using Ryu, so Netero probably was using a proportion of 15-85 in Defense nad Attack.

3- Technically, Denkosekka allows Killua to move extremely fast, this Ability just makes him go fast, if the speed is close to lightning, he is almost as fast as sound. Adding the Ability Shippu Jinrai Killua's body reacts to the enviroment BEFORE his brain goes through the process of sending information to his body.

Considering all this, Killua can react with flawless speed and timing, so if he can't literally outspeed Netero or the King, he has a chance to react to their attacks, but not for a long time.

4-

1) Netero and Meruem are in the same spot,  they seem to have an almost equal speed, with the difference that Netero moves for a short period of time faster than the sound, but overall they don't seem to have a wide gap of speed.

Killua: Only momentarily he can outspeed in terms of velocity and reaction the rest of the characters.

Feitan and Zeno: Zeno is below Feitan, since Zeno fought toe to toe with Chrollo, he himself said they were even in many aspectos. Feitan can keep a speed similar to theirs, and he isn't even at top speed, so is fair to say he is faster than Zeno.

Cheetuh: If Cheetuh was as fast as he claims, Morel and Knuckle shouldn't have been able to catch up with him in hand to hand combat after receiving some hits.
