"Type" is ambiguous in this context. Do you mean isotopes? Or do you mean states of matter? (Helium has some exotic states of matter.)
Wikipedia states that there are 8 helium isotopes, to of them (3-He and 4-He) stable.

Helium-4 has 2 electrons.
A neutral atom of helium has 2 electrons.
The decay product of hydrogen is helium. In certain types of nuclear reactions, such as fusion, hydrogen atoms combine to form helium atoms.
There are two neutrons in a helium atom, along with two protons and two electrons. Helium-4 is the most common and stable isotope of helium, with two protons and two neutrons.
Helium has 2 electrons in its first energy level.
Oxygen, hydrogen, helium, neon and xenon are some types of gases. There are many types of gases being; hydrogen, oxygen, anaesthetic gas, natural gas,helium,neon and carbon dioxide
Helium is an element, so it is made of only one type of atom.
Helium is an element (abbreviated "He"). Elements are types of substance that, when combined, form compounds and chemicals.
Helium has one kind of atom: helium.
helium,hydrogen.
Helium has 2 electrons.
Helium has 2 protons.
Helium is generally used in helium balloons and blimps. Helium is lighter than air and these items will float in air
Helium has only one type of gas (which is helium itself)
No, helium is not an example of a heterogeneous substance. Helium is a pure element, which means it is uniform in composition throughout and does not contain different types of molecules or substances mixed together.
The number of helium atoms is 6,022 140 857.10e26.
ONE, Helium is an element, not a molecule.
