The Magyar Nemzeti Galéria is at the Castle, no sure if this is the national gallery/museum, anyhow, it is exhibit art, paints and other related.
Inside the Royal Palace there are three nice museum. One of them is the Magyar Nemzeti Galeria. You can find inside it many paintings and objects that come from the Hungarian culture.
You will go to the Castle anyway, so why don't you drop by at the Hungarian National Gallery? It's for free and offers a great variaty of Art of the past centuries.
Hungarian National Museum is another museum in Budapest, which you can visit for free. And it is a very nice museum in a very nice building. It's definitely worth a visit!
