IPhone and iPad's purchased applications?

Hi, I bought some Games on my iPhone, as well as in-apps. Specifically some Hidden Object games, Visual novels and I also unlocked their extra + bonus chapters.

Recently I'm planning to get an iPad, but the problem is I'm not sure if I can redownload those Games using the same iStore account without having to pay again. Can I have two copies for each of my devices?
And if I can, are those in-apps that I purchased still available on my new iPad as well?

If the Apple ID is the same for both devices and iCloud is on, I think all the apps will be on both.
