Can my friend get pregnant if her bf used a condom and he didn't cum and the condom had no holes and she wasn't ovulating.

Only with leakage: of semen between condom & penis. Not if all semen remained within condom.

Pregnant?: Even though your friend's boyfriend didn't ejaculate, there is the generation of pre-ejaculate fluid, which may or may not contain sperm. Condoms may not have visible holes, but think about the size of a sperm and then about the size of a hole it needs to breach that condom. Doubt you be able to see that hole, but it may exist. Result is pregnancy is remote, but still possible.
