Fossils found during camping trip

[Jupiter]

Hey everyone, I found a ton of fossils littered on the ground around a cave entrance about a week ago. I took a few rocks home but can't quite figure out what they are. I've tried my best to light up the fossils for the pictures, but all the details were difficult to see when the photo was fully lit. A 10x hand lens was used to take the close ups. Ruler is metric. Geology: Bungonia Formation limestone, 427.4 - 410.8 million years old. Found in NSW, Australia

 

ROCK 1

I have 2 rocks with the same fossil. I want to say it's a type of solitary rugose coral, but still not sure.. I saw a few disc-like fossils in the rocks at the site (perhaps the top of the coral?). You can see it on both faces of the rock

 

Rock 2:

Same species are the rock 1?

 

Here's another shot of rock 2. You can see a few fossils in this, especially the crinoid (stem?) and the possible rugose coral in the bottom right. I don't know what that line that meanders through the middle of the rock is though and would love advice

 

ROCK 3

This is the one I'm absolutely stumped by. They're difficult to see, but there's faint fossils on this rock. It wasn't found near the cave entrance like the first 2 rocks but in a small eroded drainage line. Are they even fossils?

1 - Tabulate coral. Likely a favositid.

2 - Same

Other side of 2 - I see nothing clearly.

3 - faint branching bryozoan fossils, possibly.
