Official rulings

2018-03-16 You can cast Act of Heroism even if the target creature won't be able to block right away, perhaps because you're the attacking player.

2018-03-16 Untapping an attacking creature doesn't remove it from combat.

2018-03-16 Act of Heroism can target an untapped creature. It still gets +2/+2 and can block an additional creature.

2018-03-16 The effects of Act of Heroism are cumulative. If multiples resolve targeting the same creature, that creature can block that many additional creatures this turn.
