Yes, you will however want to use the split cage meathod JUST in case. Some gerbils will accept a young pup right away, others won't (an aweful lesson i learned).
An adult gerbil can hurt a young pup very quickly, so you will want to watch them and have a gloved hand ready JUST in case anything happends.
Male gerbils are 'usually' very happy to have a pup around, so most introductions with a older male and a pup goes very well. I just recently did one with 2 males pups and my 2.5 yr old lone male (lost his tank mate), it went very well.
Sex the pups early with the nipple method, and keep everything written down, this will help you down the road when u sex them at 5 weeks old, especially if a few look alike.
If there is more then 1 male going to be split caged with dad you can remove them from Mom at 5 weeks old, at this tme they will be weaned, and in a group of two they ahev each other to keep warm, and their Dad will teach them all their gerbilly skills
Good luck, and take lots of pictures, they grow super fast!
