Fractions between 0 and 1/2 include 1/3, 1/4, 1/5 and infinitely many others.
All the fractions between 0 and 1 are rational numbers
Unless it's negative, yes. Proper fractions are between -1 and 1.

An infinite amount.
Yes.
There are infinitely many. But, thanks to the strange behaviour of infinities, it set of fractions between 0 and 1 has the same cardinality (size) as the set of fractions between 0 and 100, or 0 and 10000000.
There are infinite fractions between any two whole numbers.
It just uses fractions instead of whole numbers. For example, if the numberline reaches between 0 and 1, the fraction 1/2 would be in the middle and 1/4 between 1/2 and 0.
Any one of the infinitely many proper fractions is a rational number between 1 and 0.
There are infinitely many fractions and decimals between 0 and 1.
