How to add multiple title to Python Plot using Matplotlib?

Question

So I have a code which plots images and I use subplots to show multiple images on the plot. I need to print the varible values (var1, var2 and var3) on top of the image along with the image title.

The code is something like this:

plt.subplot(2,3,1);
plt.imshow(img[], cmap = 'grey'); 
plt.title('Image1'); 
plt.title(var1)            # here we print the value stored in the var1 on top of the image next to title
plt.title(var2)           # var2 is also printed on top of the image 
plt.title(var3)

var1, var2, var3 are float values.

I tried using:

plt.title(var1, loc=('left'))

But this somehow overlaps over the image title.

The variable values needs to be printed above the image ( and the title - 'Image1' should also be present.

What is the best way to do this?

P.S. Matplotlib is to be used. Have a look at example image for reference.

It's technically not necessary, but it's good to be explicit.
