For reproducing the results, are the charts and tables in the provided slides the only ones we need to reproduce? Or do we need to produce any other result mentioned in the paper?

You are trying to reproduce the overall results of the Max Median (MM) process as outlined in the provided papers. The main point is to get the overall CAGR (along with risk statistics) using the MM methodology. You will note that the MM strategy provides CAGR almost equal to the EW index but with a portfolio of only 20 stocks. That is huge.
