Do all 4 RAM sticks have to be the same?

For the best system performance, it is advisable to use RAM sticks by the same manufacturer, of the same size, and of the same frequency.
Can you use two different brands of RAM?
Your computer is likely to run fine if you mix different RAM brands, different RAM speeds, and different RAM sizes.

How should different sized RAM be added to iMacs?
All the newest iMacs that have empty slots put the memory in pairs matching left / right so as long as you added your pair left / right but either deeper or shallower from the front glass, you should be set for optimal speeds. I’ve tried installing it the other way and couldn’t measure any differences in speed with several benchmarks.
Is it OK to install new Ram in a MacBook Pro?
You can consult Apple’s support documentation to be sure, but as long as your top two slots are filled using the original factory RAM and you installed the new RAM into the bottom slots (and you’re using the right kind of RAM, of course) then your configuration should be OK.
Which is better a pair of RAM or a single ram?
When people talk about a “matched pair” performing better, they are talking about very specific cases of two modules of the same size when compared to an individual module of the same size. For example, a pair of 2GB modules (4GB total memory) will perform better than a single 4GB module.
