I have very little knowledge about CISCO and its switches, but now I have to configure it myself.
Is it possible to allot IP address based on MAC address on CISCO CE 500 (Cisco Catalyst Express 500-24TT Switch [WS-CE500-24TT] )switches ?

You're referring to a general feature known as "DHCP Reservation"– Yosef GunsburgMay 31, 2013 at 3:27

No you need a real Cisco IOS switch for DHCP server functionality with Maunal Bindings; the Catalyst Express series switches do not run IOS

If all you want to do is permanently assign IPs to certain MAC addresses, this is simple. It's called a permanent DHCP lease. You need do this on the network's DHCP server. While the Cisco Catalyst Express 500 series switches can serve up DHCP, I don't know about advanced DHCP options; and if this is any kind of real network you wouldn't want a switch as your DHCP server.
You can find the official documentation on configuring CE 500s here. If the switch doesn't support permanent DHCP leases, then you can always assign the computer's addresses statically from its internal network configuration (/etc/network/interfaces on Debian based Linux distros). Hopefully that documentation helps you get to where you're going.
I know this isn't specifically on topic - however I believe its worth mentioning that IPv6 actually has the ability to assign an IP address based on the MAC address by using eui-64 notation.
This also does not require a DHCPv6 server as it is stateless.
