1 is a parodia
2 is a mammillaria

If by dust you mean the old areole wool that eventually becomes detached, just take it outside and blow on it or use some type of air pump as long as it is not too forceful. You will not be thanked if you do it in the room after somebody has dusted though. In nature the wind blows it away.

Some like to leave it on though, since with some species it makes them look woollier. I remember we had a branch trip in the UK to see a collection in the 1960's and the owner did a lot of showing. There was a very wooly Mammillaria there and one of our members said "you can easy get rid of that old wool" and gave it a blow. The owner nearly went mad since he had avoided top watering etc in order to leave it on as he considered it made his plant woollier looking and more likely to win in shows. Of course it only works for still air greenhouse grown plants because if you put them outside the wind removes it anyway.

It was one of the fluffy Mammillaria chionocephala types where the wool gradually detaches in age and still lies on the plant unless blown or washed off:-
