Hi i need help witch code down below. Everything works with a single button but i need to have 8 buttons and i cant figure it out. Anyone can help please ?
Thanks.

#include <PJONSoftwareBitBang.h>

const int recieverid = 45;           // Address of the reciever to send data
PJONSoftwareBitBang bus(11);         // Address of this device

const int button = 2;                // Gpio toogle switch pin
 
unsigned long previousMillis = 0;   // Mills time stored when hold pressedd
const long sendingInterval = 200;   // Sending interval when hold pressed
int holdCounter = 0;                // Counter variable when hold pressed
int holdInterval = 15;              // Max counter when hold pressed

int bounceTime = 50;                 // Debounce time for Gpio pin
int holdTime = 250;                  // Time after which hold state happends
int doubleTime = 500;                // Time which you need to double press 

int lastReading = LOW;               // Last reading state
int hold = 0;                        // Hold state
int single = 0;                      // Single predd state

long onTime = 0;                    // On time when held
long lastSwitchTime = 0;            // Last switch time

void setup() {
  pinMode(button, INPUT);
  bus.strategy.set_pin(12);        // PJON bus pin
  bus.begin();                     // Start PJON bus
  Serial.begin(115200);
  Serial.println("Starting");
  Serial.print("PJON - Sender's device id: ");
  Serial.println(bus.device_id());  // PJON this  device ID
}

         bus.update();            // Update PJON buss
         unsigned long currentMillis = millis();
         int reading = digitalRead(button);

      holdCounter++;

Install the Bounce2.h library, look at the examples and adapt them to your code.
