No. It is a rational number. Any repeating decimal or terminating decimal is rational.

Not always because any decimal that can be expressed as a fraction is a rational number as for example 0.33333.....repeating can be expressed as 1/3 which is a rational number

It is either a terminating decimal or a repeating decimal.

Always
