Currently in order to add ads to your app you will need a custom Cordova compatible
plugin like AdMob
which adds ads from admob.com. Here
you can find more information about it.
I did some more research about your ads providers and it seems that Tapjoy
has a beta plugin.
I think LeadBolt has too, but I'm not sure. I couldn't check their site because it requires to sign up in order to do that, but I found this blog
has plugin as well, but I haven't tested neither of them so I am not sure if they are Cordova compatible and whether they will work properly.
