Currently, few forward zones have created. My company has registered few 32 public IP from ISP. for example, this IP are a.b.c.96/26, meaning a.b.c.96 to a.b.c.127. I want to create a reverse zone for these subnetted IPs, how should I create so as all the A, CName, MX records that created are legistimate with PTR records?

If the CIDR mask of your network is a.b.c/26, then your zonefile name should be c.b.a.in-addr.arpa

However, you need to ask your ISP to delegate authority of that reverse block to your name servers before any internet-based queries for those IP's will hit your name servers.

could you advise why you would like a reverse zone for the public internet addresses?
You ISP would normally host this zone for you.

Hi totallytonto,

If my ISP host that reverse zone, does it also meet that I've to inform ISP for any updates/changes that I want to make for that range of IP?

Yes.  All changes for that reverse zone will have to be processed through your ISP unless you ask them to delegate authority of it to you.  Not all ISP's will do it, but it is worth asking.
