No, the "C2" molecule does not exist, because it is chemically impossible to bind two C atoms together without any (at least 2) other atoms (eg. 2 H's). The maximum number of diatomic covalent C-C bonds is three, while C atoms require four cov. bonds to obey the octet rule.
Yes, C2 is a molecule composed of two carbon atoms. It is known as ethynyl or diatomic carbon and can exist in various forms, including as a radical. C2 is not commonly found in stable conditions but can be produced in certain high-energy environments, such as in combustion or interstellar space.
C2H2N, is not a molecule per se, it is merely the empirical formula for the molecule C8H8N4, which I do not know what it is.
Yes! Since it has un-paired electrons: ) Actually C2 isn't paramagnetic. There's certain type of diagram how to determine whether molecule is paramagnetic or not. And C2 isn't. Instead C2(2+) would be paramagnetic.
An example of an atom that only exists in its molecular form would be oxygen. It is most commonly found as an O2 molecule.

It is a diatomic molecule, i.e. it exists as Cl2
Carbon 2, a molecule consisting of 2 carbon atoms.
It would be a molecule. It cannot be considered a compound because it contains atoms of only one element.
Phosphorus is an element that exists as individual atoms. It is not a molecule.
Sulphur exists as a polyatomic molecule which is S8
Nitrogen exists as a diatomic molecule (N2) at room temperature and pressure.

This is called an induced dipole. Let's say HCl, which is polar (which means the electrons like to hang out on one side more than the other), comes close to a C2 molecule. C2 looks like this C=C. If the H-Cl comes close, the negative electrons in C2 will be attracted to the Hydrogen (because it's positive), just slightly. This will make C2 polar, because of its proximity to a polar molecule.
Bromine is a molecule. It exists naturally as a diatomic molecule composed of two bromine atoms bonded together.
