 I'm sure these are just rocks but looking for people to educate me  as to why they look the way they do.  If they  appear to be anything else let me know..

Yep that bone is a birds. Most avian bones are hollow like that so that they weigh less and the bird can fly more easily

Can You post pictures of the items when they are not wet?

Can You separate the pictures of one item and number all of the pieces? Just so We can tell which is what.

I do see what looks like bone but can not be sure because the water hides the detail.

Some of them are concretions with iron content. The one below looks to be hollow ironstone concretion.

Other than the one you are calling a modern bone the rest all look like iron concretions to me.  

 

I know in Big Brook they come in all sorts of strange shapes and sizes.
