Many people are surprised to learn that the nitroglycerin in the tablets is the same chemical compound as the nitroglycerin that is used as an explosive. The chemical compound is very volatile, which means that it is difficult to contain in tablet form. By handling the tablets, the nitroglycerin may be absorbed through the skin from the tablet. Briefly touching the tablets should not be a concern, but they should not be handled excessively. Also, make sure nitroglycerin tablets are stored in a cool, dry place - not the car or the bathroom cabinet. Discard the bottle 6 months after it is first opened, as the tablets may lose their effectiveness.

No, the tablets are to be place under the tongue.
In the sense of exploding- No. The nitroglycerin is mixed with other things, and is too dilute to explode. In the sense that ANY medication can be dangerous to take- yes. If you do not have a medical condition that would require them, taking them can be very unhealthy.
Yes it can cause diarrhea, particularly the antibiotics
