I want to improve memory on iMac 27 in. 3.3 GHz, 5K retina. He now has two 4G of Ram. I want to add two 8 G of ram. Should I remove two 4 G, or simply add 8G in two empty slots? Going to have a mixed match (2 of 4 and 8 s 2) in trouble?

I want to improve memory on iMac 27 in. 3.3 GHz, 5K retina. There are now two 4 G of Ram. I want to add two 8 G of ram. Should I remove two 4 G, or simply add 8G in two empty slots? There are 4 slots for RAM.  Going to have a mixed match (two 4 and two 8) in trouble? Or will it improve my speed giving me 24G of RAM?

It will be fine as long as they are installed in pairs (and, as long as your model can handle 8 GB modules). Just install them in the empty slots. Working with word documents or online will be not much faster - you will notice the difference in speed apps to respond, with graphic design and video editing, etc or game play. The new OS versions like more RAM, so you can not go wrong there.

FYI, you do not run iOS on an iMac - Please edit your profile to show what OS version you are using. It helps the helpers.
