Is a frame with horizontal dropouts limited to a singlespeed setup? How can a rear der. be attached to the hangar to make it a multi-speed if possible?

No, definitely not restricted to singlespeed. Most road bikes in the 70's and 80's had horizontal dropouts and rear derailers. Some horizontal dropouts have derailer hanger holes, some don't (mainly on cheaper bikes). On the ones without derailer hangers, there's an adaptor thingy that fits over the axle and hangs down to provide a mounting point for the derailer. Sort of like a replaceable derailer hanger on an aluminum mountain bike...

Vertical dropouts are considered better for a geared bike nowadays, because the axle can't move around, so it'll never slip out of place or track imperfectly (assuming the frame is in alignment).

So I can attach a rear der to this frame to make it either a 24 or 27 speed?

Yes. The frame pictured has a hanger on it. Look below the dropout.

Now when it comes time to attach the rear wheel does it matter if I use a quick release or do I need a special bolt?

Though it's technically called a track end. The ones pictured above are horizontal whereas what you have are track ends (though they're far from exclusive to track bikes, especially these days).
Not to be pedantic, it's a useful distinction particularly if you stop off the at the LBS for bits 'n' pieces.

I have the same drop outs on my MTB, and I use a standard quick release with no problems.

ditto
make sure you get the QR nice and tight though, I had a friend ride right off of his rear wheel. It didn't cause an accident or anything, just had to tighten it up.
