Solaris and HP-UX are both UNIX.
All the BSDs are also real UNIX, these are good options for you to get familiar with UNIX with no outlay and on cheap x86 hardware.
freebsd
openbsd
netbsd
Are all examples, freebsd is the most friendly to get going with IMHO.
There are far to many Linux flavours to give anywhere near a complete list, but distributions like Fedora, Mandrake and SUSE are all very good as a first step into the water.
But If you really want to learn Debian and Slackware allow you to really know your system and get down and dirty. They hide very little from you and dont impose (m)any bizarre patches or default configurations.
Slackware is rather similar to BSD in its installer and the way it inits and other little nuances.
NB. Linux != UNIX, Linux is unix-like. It was designed to operate like UNIX but does not have the same heritage. Linux is Posix compatible and can run ELF binaries and has numerous more similarities
As far as commercial unices go, I cannot provide you with much information. But unless your college has copies of them for students then I strongly doubt you will be able to afford most of them.
(Solaris x86 can be found cheaply on ebay)

mkmanifest
mkmanifest(1) General Commands Manual mkmanifest(1)
NAME
mkmanifest - mtools utility to create a shell script to restore UNIX file names from DOS
SYNOPSIS
mkmanifest [files]
OPTIONS
None
OPERANDS
A list of UNIX file names to be converted to DOS name format.
DESCRIPTION
The mkmanifest command creates a shell script that aids in the restore of UNIX file names that were overwritten by DOS file name restric-
tions. DOS file names are uppercase only, cannot exceed 8 character names, 3 character extensions and do not support device names or non-
alphanumeric characters.
Not all UNIX file names are supported in the DOS world. The mtools commands may have to change UNIX names to fit the DOS file name conven-
tions. Most commands provide the verbose option (-v), that displays new file names if they have been changed. The following table shows
some examples of file name conversions:
-----------------------------------------------
UNIX name DOS name Reason for the change
-----------------------------------------------
thisisatest THISISAT file name too long
file.stuff FILE.STU extension too long
prn.txt XRN.TXT PRN is a device name
.abc X.ABC null file name
hot+cold HOTXCOLD illegal character
-----------------------------------------------
EXIT STATUS
The following exit values are returned: Success. Failure.
EXAMPLES
Assume you have the following UNIX files that you want to copy to a DOS diskette using the mcopy command.
very_long_name 2.many.dots illegal: good.c prn.dev Capital
The mcopy command converts these file names to the following:
very_lon 2xmany.dot illegalx good.c xprn.dev capital
To restore the previous file names, use the mkmanifest command as follows: mkmanifest very_long_name 2.many.dots illegal:
good.c prn.dev Capital > manifest
The previous mkmanifest command line produces the following: mv very_lon very_long_name mv 2xmany.dot 2.many.dots mv illegalx illegal: mv
xprn.dev prn.dev mv capital Capital
The good.c file name did not require conversion, hence it was not included in the output.
If these files were copied from diskette to another UNIX system, and you wanted to restore the original names, retain a copy of the mani-
fest file (captured output) so that it can be used to convert the file names again.
