First, we can't easily draw on this Wyzant platform, so I won't be able to show you the Lewis structures, but will "describe" them.
Answer: CO32- and O3 (see explanation below)
CO23- should probably be CO32- (I'll assume a typo). It has resonance structures so CANNOT be adequately described by one Lewis structure.
C in the center with 3 O's around it. One O is double bonded and the other 2 are single bonds. You can put the double bond separately on each O and that's why no one is sufficient. Put this in brackets [ ] with a 2- sign
N in the center with 4 H's around it and put it in brackets [ ] with a + sign. One structure is sufficient.
C in the center attached by single bonds to 2 H and to 2 Cl atoms. One structure is sufficient
O in center attached to 2 F atoms and put 2 lone pairs of electrons on the O atom (2 dots on top and 2 dots on bottom). One structure is sufficient. F - O - F with 2 lone pairs of electrons on the O atom.
C in the center with a single bond to the H and a triple bond to the N and one lone pair of electrons on the N. One structure is sufficient.
O - O = O or O = O - O with one lone pair on the central O. This has resonance structures so one is not adequate.
