Kia ora, I'm not too sharp on my lesser known plants so was just wondering if someone could help me ID these?

I know the first one is a Pimelea species but don't really want to hazard a guess as to which species. Could it be P.orthia? This one was growing right where the soil ends above a cliff face/ rock shelf on the coast. It was the only plant like that growing along the coast where I searched (might have walked a kilometer or so in total looking for others).

Here is an overview of the plant

And another view, there was no hair on the leaves but there is fine hair on the stems.

And is this Asplenium obtusatum? It's also growing just above a cliff face next to the sea, it's leaves are pretty leathery and...stout (?).

Sorry it's a little fuzzy, but this was how the Asplenium was growing.

And, is there any way to tell the difference between a native and nonnative ice plant?

And the last one (sorry for all the questions!)

But, what is this?
