Welcome from Australia.
We all have to start somewhere so no questions are off limits.
Stones that are a mixture of hard and soft don't go well in the tumbler, especially if you know right from the start that the soft is obviously soft, it will just grind away and leave bad undercutting. Even stones that are hard can suffer from this. Agate and Quartz are both the same mineral so the same hardness, right, nope, Agate is much tougher and more resistant to grinding than Quartz so when you tumble them the Quartz will undercut, often not a problem but it can mess up some otherwise nice stones.
Don't overthink things at the start, have a go, you will learn a lot from observing what is happening.
