Unfortunately you need to draw out the molecules, unless you can visualize how they look. Do you know how to draw them?
But right off the bat, XeF3+ will have a PERMANENT net dipole since its an ion.
CINO will have a net dipole moment since C forms a tetrahedral and since the atoms surrounding it arent the same, there will be a permanent net dipole moment.
NO2 is polar because it is bent shape and the two lone pair electrons on the N are the cause of that. if it was CO2 it will be polar since there are no lone pairs and the molecule is linear.
The rest are nonpolar
Just to let you know all molecules can have a net dipole moment, its just that polar molecules and ions have permanent net dipoles, whereas nonpolar molecules can have a partial dipole moment.
If you want more detail on how to draw molecules or be able to just look at them and know, lemme know.
