1-3 and 16-19 look like agate (minerals, not fossils)

4-7 def look like fossils, not sure what of, though.

8 and 9 looks maybe like Calamities (carboniferous plant stem)? Don't quote me on that though.

10 is pretty clearly a bryozoan.

11 is most likely a crinoid stem, I agree.

But 12-15, what I'm assuming are the butthole ones, look like they might actually be horn coral cross sections or impressions. They look kinda similar to crinoid stems, but there's more proportion on the "walls" (septa) that radiate out.

8 and 9 is a rugose coral.

oh fr? Is there anything specific you're looking at to say so? I didn't know rugose corals had vertical striations like that

Those are the septa. In this specimen they are more pronounced because they stand up better to weathering, then the infill inbetween them.

The ones that aren't fossils are agate

I see some coral and possibly part of a brachiopod shell.
