Will Family Matters season 5-9 be released on DVD? It is driving me crazy!

I had a look for DVD releases of the show Family Matters, and as your question suggests, there only seem to be DVDs going up to Season 4 in circulation.

This doesn't really bode well for the later seasons becoming available, Family Matters is a classic show, but probably doesn't pull in the viewing figures it once did - so it's possible that no DVD release is planned.

Also remember that the height of the show was during the era of VHS, another reason why DVD releases may have been limited... It's not cheap to distribute shows to a mass market, so the network would need to be certain there's a profit.

I also has a look at ABC and CBS's streaming platforms, and there doesn't seem to be anywhere you can watch any of the "back-catalogue" shows like Family Matters.

So, in this instance, your best bet might actually be to take a look at the streaming sites that I would normally steer people away from. It may take a bit of trial and error to find links to videos that work/are in good quality... But unfortunately, this seems like your best bet.
