Velen rolls 5 hits and crit, Amalar rolls 0.
On the damage step, Amalar takes 5+1 = 6.
After that, the crit resolves. It's a *separate* event. Amalar then takes 1+1 from the crit, or +2, for a total of 8 damage. Yikes.
Also, if you're playing trips Amalar and some of them are hurt, the crit will deal 2 to each of them.
