It's only sonic who becomes a werehog, in the game Sonic Unleashed.
Silver and Scourge aren't in that game, nor is the 'werehog' trait in any other game, so by default they are not werehogs.
Shadow is a loner; he is unlikely to consider anyone except for a couple of very select people as his 'friends.' Silver is better described as his ally; an ally that will quickly become an adversary if his interests or goals get in the way of Shadow's.
You have to get to the last story to become Super Shadow.
No, Sandstorm and Scourge are not mates. Sandstorm is a ThunderClan cat from the Warriors series by Erin Hunter, while Scourge is a former leader of BloodClan and a antagonist in the same series. Their interaction is as adversaries, not mates.
Ashfur and Scourge are not depicted as a couple in the official Warriors series by Erin Hunter. Ashfur is a character from the ThunderClan, while Scourge is the leader of BloodClan. Their relationship in the books does not extend to being a romantic couple.
