How to put legend?

I'm searching to find out that how I would put legend in my graph. I have drawn countour plot, quiver plot and streamline in the same graph.

I don't want to show all the data's but only want to show by legend that these three are different. So, that anyone would understand the three from the graph. I'm attaching my codes. Kindly help!

You could add separate display names to your plots , and later add legends for the entire graph and each plot would have a separate display legend.
