As long as the model converges, you don't care if it needed extra iterations to converge. That is fine.
On the time step graph, higher number of steps means smaller time increments, so the time convergence is improving from 8, to 16 to 32. I would go with 32 for the element size study. Time step = 4 is not much better than Time step = 1.
