Molecular size a bit tricky. As a quick comparison, we can use the covalent radius defined as 1/2 the distance between to identical covalently bonding nuclei. This is measured in picometers (1 pm= 1x 10-12 m). Nitrogen's covalent radius is 75pm so the length of a nitrogen (N2) molecule ought to be 4 X 75pm or 300 pm. A molecule of oxygen (O2) ought to be just a shade smaller 4 X 73pm or 292pm. So an oxygen molecule is a little less than 3% smaller than a nitrogen molecule.

This isn't the best response, as it does not take into account the different bonding which is present in the two molecules.
Although one could use covalent radius, it is more appropriate to use a covalent radius determined from similar bonding.
For nitrogen, the covalent radius for a triple bond is 54 pm.
For oxygen, the covalent radius for a double bond is 57 pm.
(Numbers from Wikipedia...)
From these numbers alone, one would expect diatomic nitrogen (with its triple bond) to be smaller than diatomic oxygen (with its double bond).
These numbers are similar to bond lengths for diatomic nitrogen and diatomic oxygen of 110 pm (~2 x 54 pm) and 121 pm (~2 x 57 pm), respectively.
Covalent radius of nitrogen = 75 picometer
Covalent radius of helium = 32 picometer
So the radius of nitrogen is double than that of helium
The bond length of a C-O bond in CO2 is 116.3 pm and the bond length of N-N is 110 pm. But there are two CO bonds in CO2 so it is larger.
Nitrogen is N2 (2 atoms) for instance Freon-13 is CClF3 and has a total of 5 atoms (1 carbon, 1 chlorine and 3 fluorine atoms). Nitrogen is smaller.
Usually in a gas, the distance between molecules is larger.
The same size as it is in a Helium atom
How much a helium balloon carries depends on the size of the balloon.
Average cost of 1 regular size helium balloon: $1
Yes, nitrogen molecules are smaller than butane molecules. Nitrogen molecules consist of two nitrogen atoms, while butane molecules consist of four carbon and ten hydrogen atoms. Carbon atoms are slightly smaller than nitrogen atoms, but four of them are definitely larger than two nitrogen atoms, and of course, there are also the ten hydrogen atoms, and although hydrogen atoms are the smallest type of atom, if you have ten of them it does contribute to the size of the molecule. Further to this, the distance between bonds will be smaller in N2 as this is a triple bond because of 3 shared electrons each, whereas it is single bonds between the carbons, elongating the bonds between carbons

Air is a heterogeneous mixture of gaseous molecules and solid particulates. Therefore, there is no single size of an air molecule. Most of air are molecules of nitrogen (N2) and oxygen (O2) gas both of which also have different sizes.
Usually in a gas, the distance between molecules is larger.
A carbon atom is about 1.5 times as big as a hydrogen atom.You'd need to be more specific about what you mean by "a carbon molecule". Carbon molecules can be enormous.
It's exactly the same size as a water molecule or an ice molecule.
depends on the size of its container and volume of helium filling it
The covalent radius of helium is 32 pico meter.
The same size as it is in a Helium atom
A helium balloon reduces in size because the helium slowly seeps out through the wall of the balloon.
because the size of helium is smaller than that of neon.
