Open source inherently means you can compile the code locally, for free. You can’t necessarily redistribute it, depending on the license, but I’m not aware of a “you can compile this source for testing and code changes only but if you use it as your actual copy you are infringing” license.
Most free software is also open source and vice versa, but not all, the difference usually lies in the licence, this stackexchange answer gets it pretty well
According to the Open Source Initiative (the folks who control whether things can be officially certified as “open source”), it basically is the same thing as Free Software. In fact, their definition was copied and pasted from the Debian Free Software guidelines.
Open source ≠ Source availiable

I am very much open to correction here.
Open Source means more than that. It is defined here:
https://opensource.org/osd/
If you use the phrase “open source” for things that don’t meet those criteria, then without some clarifying context, you are misleading people.
Free Software is not the same as “software for free”. It, too, has a specific meaning, defined here:

When the person to whom you replied wrote “free software”, they were not using it in some casual sense to mean free-of-charge.
Free as in free speech, not as in free beer
Where are all those free beer I always hear about?!
Have you tried installing homebrew?
I know where the hops go, but where am I supposed to put the cereal ? I think I ruined my disc drive
Floppy drive. That’s why you malt it first.

I think InnoSetup belongs on that list as wel.
You are talking about free softwares there are nonfree licenses which provide source code
There are apps having source public but does not have any developement practice like of open sauce
