No, you can delete the old one. Java does not remove old versions when it is updated, however I think they have fixed that now.
Java 6 has some major improvements over Java 5. Apart from the addition of additional coding libraries, it is compatible with more websites and still supported by Oracle, unlike the older version.
You can remove Java 5 if you have Java 6 and Java 5 programs should still work on your machine. However, unless you are really strapped for hard drive space, which is unlikely given the size of hard drives nowadays, there's really no reason to remove Java 5.
jdk5 is the Java Development Kit for Java SE 5. It includes the standard java installation, plus what you need to compile and make your own java programs, most namely javac.exe. It does, however, not include an IDE. as of writing this, java 5 is outdated and should java 7.

Nothing unless the "java" your talking about is coffee. The sorta answer is that java is a programming language while java 1.5 is the 5th release of the language there are i believe 7 public versions. (maybe 6 but I'm not sure.) Java 1.1, 1.2, 1.3, 1.4, 1.5, 6, & 7. (6 & 7 aren't java 1.6 and 1.7 they are 6 & 7. It drives every one crazy.) If your learning java you should be studying java 6 or 7. 6 is the better of the two if you ask me since: you'll be learning the basics of java, its more likely to be used in a school, or business environment, and if for some reason you do need to learn 7 then it's easier to switch over from 6 to 7 then 7 to 6 7 has new stuff that if you don't know about it wont hurt you how ever you plan on using said items when programming in 6 your program wont run correctly if at all. The reason while not everyone is at java 7 yet is because they have to validate it to make sure there are no security leaks and/or programs breaking.
