Rookie needing ID's please

These were grouped in with a common cordyline or two in a general foilage planter from a big box. The next post will contain an identical purchase at the same time - but with what I believe to be a different species?

 

Here's the "twin purchase" of what was just posted in the previous thread:


Both of these were 'burnt' (not sure if that's proper terminology for crotons) to the ground during January 2010 and have recovered to their current state.

 

Finally - a run of the mill variety purchased from a big box to add some color to a small island under a Phoenix canariensis centerpiece.

 

From another rookie, my guesses are:
1. Mammy
2. hard to tell, possibly a Batik???
3. Petra

 

Agreed - Mammay, Batik, and Petra
