[Star Wars] Would clone troopers hesitate to attack Jango Fett if Mace Windu hadn't already killed him?

They would have recognized him as one of their instructors​.

Probably not, they didn't hesitate to gun down their own clone brothers when the Empire attacked Kamino after the Clone Wars. It looks like the clones have a variety of control mechanisms installed in their brains, which is how Order 66 was implemented. 

So no, they may recognise him in the heat of battle, but they are born and bred soldiers who will follow their orders without hesitation.
