yes ristretto and lungo are fairly common, the ristretto is more common than the lungo in my experience. The lungo is not to be confused with an Americano, it's just a slightly bigger espresso shot (I used to make a 1:3 or 1:4 ratio - in other words, I used a single shot portafilter but the amount of coffee coming out is like a double shot) - note that in Italy, shots are smaller than overseas because we mostly use single shot baskets (7-9 grams of ground coffee) whereas in "third wave coffee" the default is to use a double shot basket (around 18 gram of ground coffee). So the Italian lungo would be just as much liquid as you would get by ordering an espresso in USA or Australia (but much weaker due to being made with less ground coffee)
