samsung and optimo

Are you asking if you can use either brand or if you can use them at the same time with some viewers using the X102s and other viewers usinng the Optimas?
It can you use either the answer is yes. I am not sure if you can have viewers using both kinds at the same time since the X102s are deigned for real projection and the optimsas are designed for front projectiion so the eyes are reversed between them.

A guy in another thread said they work together.

The Optoma glasses are DLP Link just like the X102. They will work with your set.

Can you use the DLP Optomas' at the same time as 3D Glasses that send their signal via an Emitter? Do they conflict?

The signals themselves don't conflict but some members here have found that the DLP Link glasses are reverse synced in comparison to the IR glasses.

This means that if the IR glasses are seeing the left image to the left eye for one frame the DLP Link ones will see the left image to the right eye (which is wrong).

You can't use IR and DLP Link at the same time unless you have a way to reverse the sync of either glasses somehow.
