When I see a theme I like and I click download nothing happens

Themes are handled by the launcher. some launchers can handle themes, some can't. Evidently the Huawei launcher can't. Try a different launcher, one known to handle themes (many of us here use the Nova Launcher - it handles themes and con sets).

Just look for launchers in Play and choose one that says it can handle themes. (Or look at the theme ans see which launchers are known to handle it - many theme designers list them.)
