The book says "A molecule is a group of 2 or more atoms chemically joined together." so when it says 2 or more, does it mean:
in terms of numbers or
in terms of types???

Numbers. A molecule can contain all the same atoms, for example Hydrogen molecules are just two Hydrogen atoms.

I suppose it is in terms of number
To support this look at the molecule of H2 or O2
there are two atoms in each molecule but only one type H or O

In terms of numbers. For example, consider a hydrogen molecule (H-sub-2). It has two atoms of the same type (both hydrogen), but it's still considered a molecule.

It means exactly what it says: 2 or more atoms.
Oxygen exists as a molecule of 2 oxygen atoms. Ozone is a molecule of three oxygen atoms. Carbon dioxide is a compound, the molecule of which contains one carbon and two oxygen atoms.
