As i know, there are two types of rings (E or non E). I've some questions:
- I know E can combine more than one extension tubes to use like 16E + 32E, or 16E+32E and etc. How about non E rings, also apply the same theory?
- If yes, then can I combine both E and non E rings like (8+16E, 16E +10, 32E +21 + 16E and etc)

yes to both.

Would you choose the Rollei or the hassle?

if i understand correctly, E vs non-E is only that E have electronic contact for the 2-series hassy, however, if you mixed them, you will lose the E function to 2-series, if you are using 5-series, no different then.
