Ah! The dreaded plaid, overlap lesson. It is often very challenging for students. First off, I would not worry about doing the reflected light on this lesson. Referring to the arc bar lesson, concentrate on getting the full range of tones on each cylinder (including the highlight). Also, these are round objects so there would not be a shadow on the horizontal cylinders to the left of vertical cylinder because the light source is coming from the left. There should be shadows on the vertical cylinders to the right of the vertical cylinders because the vertical cylinders would be casting a shadow on the horizontal bars that are behind them. Those shadows on the horizontal back cylinders should curve. Narrow on the bottom and curve out as the go up. This will illustrate the cylindrical shape. Setting up a model of things at home like pencils, pens or chopsticks and lighting them properly can be a great help!
