You could do it by shifting the position parameter of a bar-plot so that they are adjacent to each other as shown:

matplotlib.style.use('ggplot')

fig, ax = plt.subplots()
df[['a', 'c']].plot.bar(stacked=True, width=0.1, position=1.5, colormap="bwr", ax=ax, alpha=0.7)
df[['b', 'd']].plot.bar(stacked=True, width=0.1, position=-0.5, colormap="RdGy", ax=ax, alpha=0.7)
df[['a', 'd']].plot.bar(stacked=True, width=0.1, position=0.5, colormap="BrBG", ax=ax, alpha=0.7)
plt.legend(loc="upper center")
plt.show()
