Gloucester is a problems unless Edward IV in his final 15 years revises the Neville settlement of 1475 - Richard's hold on those lands is exceptionally weak after the death in may 1483 of George Neville former Duke of Bedford and the death of his own son (if it happens as in otl) with those deaths his hold on those estates is reduced to a life interest (reverting to Lord Latimer who is a minor) - which significantly reduces his power and patronage.
Now Edward may well revise the terms but there is no guarantee that he will. And any dispute over the inheritance will involve Dorset (the Queen's son) who had the custody and marriage of the Earl of Warwick.
Buckingham - he is a probable focus for rebellion however he has been kept from his family's traditional role (although given he was a minor until the early 1470s) particularly in areas dominated by those closer to Edward. But much of his present reputation descends from the wrongly named rebellion against Richard in 1483 and the support he had during that revolt largely (though not wholy) came from supporters of Edward IV who wanted to restore his son (and their own influence). He also wants restoration of the Lancastrian half of the de bohun inheritance which Edward kept for himself.
Henry Tudor - Assuming he avoids getting caught up in any Anglo-French conflict then I think a return home - at huge cost to his mother in land deals with Edward i suspect. Perhaps a restoration of his title of Richmond (though it had been given to Gloucester) - as to his uncle depends if Edward wants to annoy the Herbert's by giving Pembroke back to Jasper.
Defunct Lancastrian rebels - Northumberland was restored to his titles and served Edward IV loyaly throughout the 1470s so he is an unlikely rebel the main likely rebel is the Earl of Oxford, the last real remaining loyalist, but was a prisoner of Edward IV and his influence had been broken (in OTL he escaped in around 1484 and joined Henry Tudor).
