Query on Arduino based Communication protocols

I am using Arduino Nano for my project which requires three modules to communicate serially.If I use hardware serial,AltSoft serial and software serial (or) NeoSw serial will be a problem?Will they block each other while transmitting or receiving the data ?What are the other alternatives to serve this purpose?

Start again with a MEGA, four hardware ports, no limitations.

An external serial port expander if you’re locked to the nano…

If you’re a real masochist, you may be able to mix & match, but I wouldn’t.
