Answer 1

Let say the graphicLayer is the map graphic's layer, the id attribute is named "id" and you want to remove the graphic with the id 0;

var graphicLayer = map.graphics;
var idAttribute = "id";
var idValue = 0;

var toBeRemoved = graphicLayer.graphics.filter(function(graphic) {
  return graphic.attributes[idAttribute] == idValue;
})[0];

graphicLayer.remove(toBeRemoved);

You could create a function for doing this in batch

function removeGraphicById(graphicLayer, idAttribute, idValue) {
    var toBeRemoved = graphicLayer.graphics.filter(function(graphic) {
      return graphic.attributes[idAttribute] == idValue;
    })[0];

    graphicLayer.remove(toBeRemoved);
};

var idsToDelete = [0, 1, 2, 3, 4];

idsToDelete.forEach(function(id) {
  //using map.graphics layer for instance
  removeGraphicById(map.graphics, "id", id);
});
