they are all in my /usr/lib/jvm/.. file in my ubuntu machine. Can someone explain the differences between these 4 files and why the file called java1.8.0_91 isn't considered a JDK? I came across these files while finding a JDK for android studio.

Most of these directories are symlinks to each other. You, probably, have two JDK/JRE installed: Open JDK and Oracle JDK. See here and here for difference between Open JDK/Oracle JDK, and between JDK and JRE. java1.8.0_91 is probably JRE, not JDK.
