What types of capital punishment are still being used?
Depends what country you are in. Europe is fairly civilised and therefore there is no such thing as capital punishment anymore. Less civilised countries like the US and Afghanistan will quite readily kill its citizens for crimes (at least allegedly) committed. Edit: sorry methods of death can be street killing by shot to the head, lethal injection, hanging, rape & murder, electrocution, starvation you know, all the good stuff that mankind has aspired to.
