1) "Out here" refers to just being some where. It's just a way to talk. Also, it implys that Washington County, Tennesssee is in a more rural part of the state. They could have just as easily said "We are here, in Washington County, ..." 2) Your friends being late would be disrespectful to you or disrespectful towards you. You would likely say, "That was very disrespectful" . If for example, their car broke down or the bus was late, something that wasn't their fault you could say, "That was lame" referring to the reason that caused them to be late. "Sorry we are late, the car broke down" "Oh, that's lame". In that case it was not their fault they were late to meet you. 3)I would agree that "on a scale" sounds more natural, I can't say if there is anything wrong with the first but it does sound strange. 4) If you just wanted to say that, I would say "I messed up on the/your/his/her remodel" I hope this helps!
