Yes, imaginary numbers are a subset of complex numbers.
No. For example the number 1+i. Pure imaginary complex numbers are of the form 0 + a*i, where a is a non-zero real number.
A complex number can be a pure imaginary, or a pure real number, or a combination of the two. The form for a complex number is a + bi, where a & b can be any real numbers (so if a = 0, then the number is pure imaginary; and if b=0, then it is a real number).
Yes. The number 1 + i is imaginary but not pure imaginary, while 5i is pure imaginary.
