A number of Carboniferous fossils from Britain I'm unsure about.

I have been trying to identify my fossils finds from over the years. Most I can do at least to class level, sometimes species, but there are just a few that I don't really have any clue on. All the ones shown here are from Carboniferous sediments.

These are: 

1.  
From Salthill Quarry, Clitheroe, Lancashire, England.
Among the many crinoid fragments, and even Fenestella bryozoans and some articulate brachiopod, I found this small branching structure. The stems are thin, branching into widened cups (roughly 1cm wide, I can get more accurate measurements if needed). It's like a coral, except like none I know of. Seemingly no septa like a Rugose coral, and not exactly the form I though a tabulate would take. Almost wondered if it's a huge bryozoan. No clue.

2.
From near Lochranza, just north of the Diplichnite on the Isle or Arran Scotland.
Found among some small rugose corals, brachiopods, cylindrical crinoid fragments, and a site where trilobites can in theory be found in the reddish limestone. The shape is coral-like, but texture more sponge-like. A poriferan? Maybe even bryozoa?

3. 
From in Notts II, a cave near Ingleton in the Yorkshire Dales.
Among many large rugosa similar to Dibunophyllum and Axophyllum, along with some brachiopods. These structures grow large (compare to photo with my hand in) and have no clear structure other than a spongy apearance and seemingly growth rings as it gets larger from an origin. Poriferan?

4.
From brittle shale layers in the river Hodder near Hodder Place, Stonyhurst, Lancashire, England.
From a site known for its unusual Phillipsia trilobite specimens, in the Rad Brook formation, among many tiny cylindrical crinoid fragments and a few barchiopods. Both of these are tiny, the flat pitted object being maybe 3mm across at best, and tge drome maybe 5mm. Perhaps a tiny bryozoan for the pitted thing. Not a clue for the textured dome.

Any suggestions with any of these would be very much welcomed. Thank you!

It is more sensible to put each comment below each photo concerned because we are forced to scroll to know what you’re talking about. Thank you.
