In diagram 5, fingerings for the left hand (LH) and right hand (RH) are added below the tab. The symbols I use are T for the thumb, and 1 to 4 for the four fingers (1 is for the finger closest to the thumb).

So in this example, all the notes are being plucked alternately by the first and second fingers of the right hand. The left hand fingering is not marked for bar 1, because all the notes are played on the open string. Then in bar 2, the recommended fingering has finger 1 of the left hand at fret 2, followed by finger 2 at fret 3, followed by finger 4 at fret 5.
Try it out.
I am naturally a finger picking guitarist. If you prefer a pick, there are good resources around to help you use it correctly. In the meantime, the main skill you should aim to acquire is an accurate up and down alternating pick. So in an example like the above one, try playing down where finger 1 is marked, and up on finger 2.
By the way, did you notice the rhythm pattern? In the first bar there are 5 notes spread over 4 beats. The layout shows that the last 2 notes are only half a beat each. And in the second bar the last note runs for 2 beats.
