Identifying Corals

[SpaceInvader98]

Hey guys I'm a new reefer here ( 6 weeks ) can you please help me identify these corals?

Trachyphyllia corals. LPS, low in the tank, low indirect flow. Occasional feeding of meaty foods when showing a feeding response.

How much are the prices of these corals? How much do you think these ones I showed cost?

That's subjective to the location and buyer. I would personally pay 60 to 100 for those. But again, just my opinion.

The first one on the left costs 40$ should I go for it?

Absolutely, that's a nice coral.

Hello coral gurus. I am woefully ignorant in coral knowledge. I purchased all of these from 3 different lfs. In all cases I was told these are "easy" and no one seemed to know at the time what exactly they are.
I was told both of these are "leather" corals but no other info.
Are they in the best spots in the aquarium? Do they have names? How far should they be from other stuff?

And what are these?
Same questions are they in ideal spots?
