Yeah, real numbers are any number you can place on the number line, so that includes fractions, irrational numbers (numbers that have no fraction representation) like pi, etc.
Imaginary numbers require an extra dimension on the number line, and they are the result of square rooting negative number, which cannot be done in "real" mathematics (hence the term "imaginary"). The square root of -1 is i and all imaginary numbers are multiples of i.
Complex numbers are numbers that have a real and an imaginary part, so the number 1 + 2i is a complex number, for example.
