If you are flying on AA you are not going to be able to check in with BA, unless this is some very new T5 benefit that I'm unaware of.
As to T5 check in desk opening times, I would go by the website, 6am sounds correct now that the first DFW flight is departing earlier. 6:30am would've made sense back when it was only JFK and the ~9:30am departure was the first one out.
