Is there any way these columns with the top and bottom brackets can be supporting columns. If I can't tell by the brackets, I will need to break into their drywall at places to see if it or another beam is supporting. I want to remove them.[Images
Yes, those posts are probably supporting the beam (above). You’ll need to determine the load on the beam, size of existing beam, span from post(s) to wall, and location of footings.
The post without the metal base connector may just be decorative...to match the other post. However, either hire an architect or structural engineer OR submit more info regarding beam sizes, spans, footing locations, etc. for additional help.
