Is it possible to assign many pins to one variable?

Projects Programming
7

Now whenever i run this

int a1 = 2, b1 = 3, c1 = 4, d1 = 5, e1 = 6, f1 = 7, g1 = 8;
int myInts[7];
int nine[] = {a1,b1,c1,d1,f1,g1};

void setup() {
Serial.begin(9600);
for(int i = 2; i < 9; i++){
  pinMode(i, OUTPUT);
  digitalWrite(i, LOW);
  }
}

void loop() {
digitalWrite(nine, HIGH);
delay(500);
digitalWrite(nine, LOW);
delay(500);
  }

It says this as an error

exit status 1
invalid conversion from 'int*' to 'uint32_t {aka long unsigned int}' [-fpermissive]
