No, they are the only numbers that are NOT rectangular in shape. (I think you knew this and screwed up your question.) That is, all non-primes can be arranged into the form of a rectangle - e.g. 21 can be organized as a rectangle with dimensions of 3 x 7. But prime numbers cannot be organized as rectangles.
There is no such formula. Rectangular numbers are composite numbers and there is no known formula that will generate either composite numbers or prime numbers.
No. To be rectangular a number must have two factors greater than 1. If it has two factors greater than 1, it cannot be prime.

The prime numbers and the squares of primes between 2 and 20: 3, 4, 5, 7, 9, 11, 13, 17 and 19.
The second and third rectangular numbers are 6 and 12
Rectangular numbers are a subset of composite numbers. The squares of prime numbers will be composite but not rectangular.
There is no such formula. Rectangular numbers are composite numbers and there is no known formula that will generate either composite numbers or prime numbers.
rectangular numbers are numbers just displayed in the shape of a rectangle e.g take the number 6 it can be shown as: ** ** or ****** **
No. To be rectangular a number must have two factors greater than 1. If it has two factors greater than 1, it cannot be prime.

The question is ambiguous since a rectangular pyramid and a rectangular prism will have different numbers of flat surfaces. There is no indication in the question which shape is intended.
a shape that is rectangular so deal with it
Prime numbers are not shapes. The closest thing I can think of is a polygon with a prime number of sides.
rectangular
the shape of the base of a rectangular pyramid is a rectangle.
Rectangular
They are in a rectangular shape because it holds more room than any other shape.
