no, atoms don't have to have neutrons, neutrons are supposed to be neutral so it wont change the charge of the atom if you add or subtract neutrons from an atom. what will change is the mass number of the atom.
Most hydrogen atoms don't contain any neutrons. Deuterium atoms are hydrogen atoms with one neutron each, and tritium atoms are hydrogen atoms with two neutrons each, but most hydrogen atoms are protium atoms, with no neutrons at all. All other atoms in the universe except protium contain at least one neutron each.
The atoms of ALL elements contain at least one protons. The atomic number of each element is a count of how many protons atoms of that element contain. Thus, in answer to your question, there are NO metals that do not contain a proton.
All the lithium atoms contain the same number of protons.
All matter is made of atoms.

Yes. All materials you will find on earth contain atoms.
The basic building block of all compounds is atoms. Compounds contain atoms of at least two different elements bonded to one another. Thus, atoms of elements are what form compounds.
All the lithium atoms contain the same number of protons.
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.
Heat is the vibration of the atoms or molecules that make up things. As all atoms can vibrate and all objects are made of atoms, all objects contain heat energy.
All matter is made of atoms.

Yes, all the compounds contain different types of atoms.
