Yes, fluorine can form a non polar bond, only with another fluorine atom, in fact fluorine gas.
yes with itself
A fluorine atom can never form a nonpolar covalent bond because if you were to use the electronegativeity chart and subtract the second highest number with Fluorine, you get numbers that range from 0.6 (polar covalent) to 3.3 (ionic).
Answering this question requires distinguishing between two meanings of of the word "single" in the phrase "single covalent bond". If the normal, non-chemical meaning of "single" is applied to this phrase, the answer is "yes", because N2 contains only one covalent bond. However, covalent bonds are themselves classified as "single", "double", and "triple" according to whether they involve sharing one, two, or three pairs of electrons, irrespective of how many such bonds may occur in a molecule. The bond in N2 shares three pairs of electrons, so that it is formally correct to state that N2 contains a "single triple bond". To avoid the paradox, it is preferable in chemical writing to state that N2 contains "one triple covalent bond."
Zinc, as with all metals, reacts to form ionic bonds with other elements.

No, they are both halogens and nonmetals with a electronegativity too close together to form an ionic bond. They, if ever bonded, would form a covalent, or polar covalent bond.
