Use Screws Or Hammer Nails Back Into Joists?

Answered
Looks like the majority of the nails holding my duct work to the joists are popping out causing a slight sag in the duct work. should I simply hammer the nails back into place or replace them with screws? Looking down the line, it appears most are at least a quarter inch out of the joists.
