Lazio, Napoli, Juventus, Inter, Milan and even Roma all getting a win is quite possible. A few risky ones in there, Inter will be playing Torino and they do look great, they were leading the league until the last loss, if they didn't lose the last game they would have been leaders anyways.
The top four is the top four we all know, but Roma will be playing against Monza, to be fair I do not trust Roma to win games and I find them not good at all this season but Monza is the last team and has no wins at all, so while Roma doesn't look good, they look good "enough" to beat Monza as well. If you bet on all of these, as a parlay, then you get 18.00+ odds, which is huge. Milan is the one with the worst chances but I think they will win this one.
