I don't know much about pipes and joint sizes. With that said. I have the pipe below, and I've broken both the down stem and the bowl. This says it has a 18.8mm > 10mm. I've had trouble finding 10mm male bowls. Can I buy a down stem that is 18.8mm > 14.5 mm and fit a 14.5 bowl? I appreciate any help! My pipe/bong is below.

Yes you can. Make sure you get an 18mm to 14mm , with a bowl to fit the 14mm. Why not just get a strait 18mm to 18mm stem with 18mm bowl?
Reguardless of what you do, you can do pretty much anything with glass pieces. You want to throw 3 ash catchers on your bong...all the power to ya man! Just make sure you get whatever that fits your bong, which is 18mm you said, you can diffuse down to 10mm, or go strait into a 18mm bowl like a said, anything is possible.
Well, that's what I needed to know. I just didn't know if I was stuck buying the same downstem/bowl size. Thanks for the reply!
