I read and came up with random ideas... naturally feel free to shoot down...

Warning Randomness Below

Devon - Thrives on attention and is a year older than him, he probably strayed away from actually interacting with her in his first years.  As collecting gossip and being to near would be something he definitely saw as a risk.  Plus muggle phobic would be a second risk as he knows his background which he has certainly tried to hide would put him at a disadvantage.  In his third or fourth year he probably started risks of being around her if she did something big mostly to observe others reactions to her.  IC I am rather sure his father being a sqiub is not public knowledge - unable to do magic though may be.

Lindsey - He has probably observed her tendencies for perfection and as perfection is something he holds in high respects.  As perfection is eliminating things wrong others can observe.  I cannot even guess on this one so I think this is one of those we will see what happens in the first shared thread.

Quinlan - If they had a common class it sounds like Quinlan is someone Dakota would gravitate towards sitting next to.  As quiet, and attempting to avoid having attention focused on them would be ideal to sit next to - so attention would not be drawn to Dakota.  Though both being quiet not sure how they would have met besides a common class or activity.

Pete - If he has been this way since first year - unless Pete did anything to make Dakota look bad - Dakota would probably attempt to be at least acquaintances with him, possibly friends if you are interested.  As even though Dakota avoids attention being friends with someone as outgoing as that probably seems normal, and the opposite would be more likely to be noticed.  Plus OCC I am all for Dakota being dragged about to do crazy things.

Gavin - Since Gavin is a couple years older than him and not socially forward there is a chance in Dakota's earlier years he may have gone and talked to the boy.  Probably in his first year a congratulations for a good quidditch game and such.  Dakota would have probably observed the boy's tendencies towards sensitivity which would have made him less threatening.  No idea where that would have taken there relationship though I am sure it is something Dakota has observed and quietly tried to use at least once.  Another one where I really have no idea beyond how they were probably introduced.  Though Dakota would probably just be quiet about the game not supportive on Slytherin's loss.
