Enhance my stacked barplot title, and flip legend

[Clunk_Head]

I've got most everything in order with my stacked barplot

but I am missing two things:
1) Can I have multiple title lines, each to which I can apply different text properties?

plt.title("Title line 1",fontsize=20)
#One of them will be bold
#Two of them will be one color and the third another color
#Two will be center aligned and the third left aligned

2) Can I flip the legend upside down?

plt.legend(names[1:])

I've tried:

plt.legend(names[1:], handles[::-1], labels[::-1])

but it gives me an error:

Error:
    plt.legend(names[1:], handles[::-1], labels[::-1])
NameError: name 'handles' is not defined
