Yes. And since Real numbers are a subset of complex numbers, a complex number can also be a pure real.
Another AnswerYes, for example: (0 + j5) is a complex number, whose 'real' number is zero.

True. Complex numbers have a real part and an imaginary part. If either one of these is zero, the complex number will be a pure real or a pure imaginary.
If a number is pure imaginary then it has no real component. If it is a real number, then there is no imaginary component. If it has both real and imaginary components, then it is a complex number.
A pure imaginary number is a complex number that has 0 for its real part, such as 0+7i.
No. All Complex Numbers are of the form a + bi where a and b are Real Numbers and i is the square root of -1. So only ones where a = 0 are pure Imaginary Numbers.
One is a complex number and a real number.
