Multiple problems

Spoiler below!

Entity tab on your lever --> ConnectionStateChangeCallback --> "PullLever1"

void PullLever1(string &in EntityName, int alState)
{
if(alState == -1) && GetLocalVarInt("LeverX")==0) // Correct pull
{
SetLeverStuckState("LeverName", -1, false);
AddLocalVarInt("LeverX", 1);
PlayGuiSound("CorrectSound", 0.8f);
return;
}
else if (alState == 1) && GetLocalVarInt("LeverX")==0) // Correct pull
{
SetLeverStuckState("LeverName", 1, false);
AddLocalVarInt("LeverX", 1);
PlayGuiSound("CorrectSound", 0.8f);
return;
}
else
SetLeverStuckState("LeverName", 0, false);
SetLeverStuckState("LeverName2", 0, false);
SetLeverStuckState("LeverName3", 0, false);
SetLeverStuckState("LeverName4", 0, false);
SetLocalVarInt("LeverX", 0);
PlayGuiSound("WrongSound", 0.8f);
//Reset levers to state 0?
}
}

This process has to be repeated for each lever. The difference will be the name as well as the variable "LeverX".
LeverX decides the order - 0 for the first, 1 for the second, 2 for the third, 3 for the fourth.
else if (alState == 1) && GetLocalVarInt("LeverX")==1) // Correct pull
else if (alState == 1) && GetLocalVarInt("LeverX")==2) // Correct pull'

Etc.
As you may notice, my scripting is kind of blunt.
