pic #1 looks like the top piece is a lobophyllia with great growth, under that appears to be a green chalice, i cant quite make out the eyes, but if theyre orange its a mummy eye chalkice, pic #2 is a red chalice, ive seen them listed before as fire chalices, pic#3 i assume your asking only of the centered coral, which ive seen listed as flame thrower chalice or fire and ice chalice, pic #4 apprears to be a pink chalice with a bluish gray hue aroiund the edged, people can make up so many names for this but try bubblegum chalice you might find some info on that. hope this helped -matt
