According to Debian policy, limits for both UID and GID numbers (User IDs and Group IDs) are a maximum of 65535. Is there a way of increasing this limit?

I'm studying for RHCSA and am confused by a statement I came across in some training material:
There is no practical maximum RAM, as theoretically, you could run 128 TB of RAM on RHEL 6. But that's just theory. The maximum RAM supported by Red Hat on RHEL 6 is 16 GB on 32-bit systems and 2 TB on 64-bit systems.
I am starting to migrate about 1000 user mailboxes from an Exchange 2003 cluster to a new Exchange 2010 SP2 and I'm trying to figure out how to set mailbox size limits based on user roles. My idea is to divide users into 3 roles by Active Directory groups, High usage (1 GB limit), Medium (512 MB limit) and Low (256 MB limit).
I am trying to provide support for core dump on my ARM based target ,I have read about both /etc/limits and /etc/security/limits.conf ,My target file system doesn't have the later one on to it ,So I have made below changes to /etc/limits
After adding this line to /etc/limits was expecting the generation of core file but ulimit -a shows me
make a soft 64GB limit for resident memory (so inexperienced users will get their run-amok processes killed, but experienced users can raise the limit for memory hungry processes)
raise the hard limit for nofile, but keep the soft limit at 1024 (so if a certain program needs more filehandles, the user can grant them, but run-amok programs will not get them).
I'm trying to install the oracle 11g database (I believe this is the lastest) on a fedora 17 on virtual box (latest version) on Windows 7 and I'm bumping into the following limits:
(1) Hard Limit: maximum open file descriptors: exected value 65536 Actual value 4096.
How do I adjust this parameter?
(2)Hard Limit: maximum user processes: Expected value: 16384 Actual value: 11670.
How do I adjust
