This isn't how plugins work. I'd recommend changing your host though, plugin limits are a terrible idea. Minecraft hosts in general are a terrible idea unless you're not confident with running servers (or on a tight budget).
If you're talking about a free server, then sadly you most likely can't upload custom plugins. They have to approve public ones too, so you wouldn't be able to add it from the plugin list.
