They are from the aulonocara AKA peacock family. The 1st one looks to be of aulonocara hansbaenschi AKA red shoulder peacock. The 3rd pic looks to be some sort of aulonocara jacobfreibergi.
sweet peacocks aye.. sorry cant help you on the ID's but if you go to cichlidforum.com search the aulonocara family drop down from the list and go thru the list you may find some very close to what you have..
