Help me I.D. these 3 peppers

[Flomaster]

one of the guys I work with heard I like hot peppers so he brought me a couple from his garden, I'd like to try and grow each variety from the seeds in these.
 

 
I am told this one is Devils Tongue

 
This one is Scotch Bonnet

 
This one is Caribbean Habanero

 
 
I don't think these are ripe, will they ripen off the plant and can I harvest the seeds and start my own plans from these peppers?

the one on the right looks a little like my mustard habaneros
