Not necessarily, one condom will do the trick! 2 condoms would usually create more friction between the two which will cause the condom to rip.
Using two condoms is actually less effective than one condom alone. This is because the two condoms will rub against each other, creating friction, then can create a hole and cause them to fail.

Two pies are better than one pie!
One is lonly, two has company.
