What are these skeletons of?!

Hey i took these from my mom's house as I want to make them into Zoa Garden rocks specifically the Rounder one...

If anyone could ID these skeletons for me it would be greatly appreciated I want to obtain more of the roundish stuff but hard to do if I don't know what it is lol...

Thanks in advance..

I'm going with Goni on the first one and some type of Brain coral on the second.

Def a brain or LPs on the second, ?a trachyphyllia?. The first I thought could be a Porites. It was a common live rock in the hobby from hawaii before regulation. But goni would be a good guess.

Awesome thanks for the help I am assuming the goni, trachy or porites would all have a similar skeleton the "round" one in the picture just as that's all I'm really looking for is the overall shape...don't really want to pay $12/lbs for tonga branch etc...would rather just ask locals for their skeletons
