Help name 4 coral

[derick]

Can anyone tell me the names of these coral and maybe where they should be placed?

number 1 is a torch and depending on your lights it can be placed high or low. I have mine in the sand but my lights are strong. They like like, i keep medium flow on mine. If you search my name in the LPS section you will see mine on ground with a hammer which is the same family coral.
number 2 looks like an acan... I have 1 but it looks like it was receding, i had it on the floor and i have moved it up much higher since. It has stopped receding but it is not coming back yet.
The rest i cannot tell by the pictures and my in-expertise

I would say 3 trupet or candy cane leaning toward trumpet 4 duncan to finish it off and I would say sand bed for placement
