1. The smear bands with hypersensitivity as your mentioned have the greater molecular weight than RNA contamination which is less than 100bp in size. I believe that these are impurities, such as proteins and polysaccharides, migrating from the lower wells.  

2. The relaxed circular molecular form, and the full-length linear molecular form of the uncut plasmid usually run very close together and are not always resolved from one another. The upper band is the combination of relaxed circular molecules and full-length linear molecules. You are right on the other bands.

3. The genomic DNA is 23kb or greater in size. In general, it is easy to separate the gDNA molecules and plasmid molecules on an agarose gel.

4. They are the relaxed circular molecules and the full-length linear molecules running as separate bands.
