Fossils from my birthday fossil hunting trip

I'm an amateur, so I'm not positive if these are even all fossils! So if you know what they are, please feel free to educate me and everyone else! I can put what i think I'm seeing, but it's really just guesses.
These two red, elongated pieces i thought were either coral pieces or those tube worm type animals, crinoids.
These are from north eastern Texas, an area known for fossils, Ladonia Fossil Park.

The snail shell is recent, it's very lightweight. The top, large red one, i believe has fish scales and a fin. The large one towards the left is vertebrae. The upper right is a base for those tube worm critters. Next, medium, mid right, is bone. Thinking it's possibly also vertebrae, but a different animal, maybe fish? Bottom right, not sure if it's a fossil, or a rock, but i liked it.

Top is a vertebrae for sure, when initially picked up i thought it was older, but I'm doubting myself on it now. The two yellow/ orange ones are based for those tube worm animals (i used to know the name, i blame covid for forgetting words). *i just recalled their name before posting this! Crinoids!* Lower left is a shell. Upper right is another shell. Middle right appears to be bone, fossilized. Lower right is either shell or turtle plastern.

Top middle had a break on it that looked like it mint have been used by humans. Lower middle I'm not sure what it is, tooth? I dunno. I picked it up though so here it is. Lower right, another bone piece or rock? That's the game we're playing! Fossil or rock?

Closer view of what i think are fish scales and a fin. The internet will brutally correct me if I'm wrong.

Alright, do your thing imgur, what did i find? I'm really curious about the vertebrae and the possible fish scales.
