what are the difference between centos, red hat and Solaris?

CentOS / Red Hat relationship easily researched through Googling...

Solaris isn't a GNU/Linux, it's a UNIX. Again GIYF. Top result is the rather informative wikpedia entry.

CentOS is now sponsored by Red Hat. Basically, it's Red Hat without any support and without the annual subscription.

Solaris is now a proprietary system: the free, open-source equivalent is OpenIndiana. I believe it can run most Linux software (unlike, say, BSD) but the hardware support is poor.
