He's very durable and has great strength, he didn't have all that many strength feats in the shows/movies, but I vaguely recall him doing some pretty impressive moves, forcing metal powered doors apart, being one.
In ST: Insurrection, he was pretty badass and was able to take out many armed men with a combo of speed and shooting skill. He's also trained in at least Star Fleet H2H figthing tactics, which have proven affective against Klingons and the like.
He could likely get passed the first battle.
Ten drones will be a problem, really depends on the surrounding and if he's able to employ his speed to avoid and only fight 1-2 at a time.
Not sure what a T1 is.
Could likely defeat Sonny using his greater intelligence and deductive skills to find a weak spot.
Robocop is built like a tank, but he's slow and Data could crush his jaw in.
T800 is slow and Data could likely bend the thinner pistons that control the movement.
Same for the T850.
Ironman will be problem if he's stronger(likely is) and I'm doubtful if Data could damage the armour before Tony severely damages Data.
