Actually, just a JRE for the current versions of Tomcat. 5.0 and below
required a JDK.

No, you have to use a JRE built for Linux.

A JRE consists of much more than class files; the core of the JVM
(object allocation, garbage collection, byte code execution, etc.) is
written in C and C++ (plus a smidgen of assembler); the JRE API handlers
that interface with the system are typically written in C.
Consequently, you must have a JRE that has been built for your specific
platform.

Yes, assuming your OS supports some form of IA32 compatibility mode.

This has nothing to do with Jikes - it's not needed. The 5.5 and above
versions of Tomcat come with a built-in JSP and Java compiler.

No - download and install a real JRE for Linux from the vendor of your
choice. (If you're running Red Hat, I would expect them to have one
available.)

No - none of this has anything to do with Jikes.

Yes, version 5.5 or above.
