Answer 1

If these are the only 2 times throughout your entire script that l and l2 are set, then you can check after setting the values.

var l = false;
var l2 = false;

var imm = new Image();
imm.src = "b.png";

imm.onload = function(){
  l = true;
  if (l && l2) {
    myFunc();
  }
}

var imm2 = new Image();
imm2.src = "c.png";

imm2.onload = function(){
  l2 = true;
  if (l && l2) {
    myFunc();
  }
}

function myFunc(){
  //do stuff
}
