On that list, I've really only extensively tested emulators for NES, SNES and PS1.
For NES, I use John NES Lite. NES emulators are plentiful, of course, but of the free ones, I like the UI of John the best.
For SNES, I use SNES 9X EX+. Free SNES emulators are also pretty easy to come by, but SNES 9X is obviously a name brand so it was among the first I tried. Works flawlessly and has good configuration options.
For PS1, I actually use an app that costs a few dollars. I tried some free ones, but experienced various problems like crappy button configuration and slow emulation. I settled on ePSXe. It doesn't cost much, $3.99 I think. The devs regularly release updates. Emulation is very smooth. Sometimes I've noticed that the music doesn't sync up correctly, but I rarely have the volume turned up on my android, so this doesn't affect me really.
Also, I recommend using a Bluetooth keyboard or, if you can figure out how to make it work (I never could), using a PS controller (or whatever) unless you plan to only play RPGs. No matter how ergonomically you configure the on-screen buttons, they can be pretty frustrating for fast-paced games.
