HT is really about what sounds good to you. Things will sound more realistic with 5 identical speakers, but it's by no means the only way to go. Most of us using classic JBLs have to make do with with what we can because there were no matching centers until fairly recently.
If you have a newer receiver with a mic that can auto-equalize each channel then it's even easier to just use something fairly close. You might be surprised how good it sounds with something as basic as a S-Center and 2 S38's for surrounds. They are easy to find used and pretty cheap.
