What are the transaction fees for these coins?
It can be different and change all the time. You need to check at exact moment when you want to send. During last spam attack on bitcoin fee were ridiculously high. After attack stopped they became lower. But after implementation of segwit they became even more smaller. If you send from segwit to segwit address you can pay ridiculously small fees.
Also it depends from wallet what you use. Some wallet does not allow to change fee... Lot of factors and difficult to answer your question
