The one in the center showing me and my ally's health

it is just the party/Raid frame introduced by Blizzard with Cataclysm
If you are playing Wotlk you may replicate that with this: http://forum.warmane.com/showthread.php?t=317421
or this: https://github.com/RomanSpector/CompactRaidFrame
(I have NOT tested any of them. Do it at your own risk)

the one showing ennemy cooldowns ( fear, silence )

It might be Juked, omnibar, Improved interruptbar and many other

Its a very nice addon, sadly i cannot get it to work combined with omnicc ( aura timer isn't showing) even tho i ticked the ''use with omnicc'' optionj
