The most common use for a TXT record is to store SPF (Sender Policy Framework) data.  SPF data controls which IP addresses and servers are allowed to send e-mail from your domain, this prevents others sending emails out acting as if it was from you.  For example you could set up a TXT record on mywebsite.com that contains the internet IP address of your computer at home, this would mean that mail claiming to be FROM: something@mywebsite.com is only allowed to come from your home IP. If the user tried sending mail from a device with a different IP address then it will be rejected as that IP address is not included in the TXT record.

CNAME records can be used to alias one name to another.

For example, if you have a server where you keep all of your documents online, it might normally be accessed through docs.example.com. You may also want to access it through 
documents.example.com. One way to make this possible is to add a CNAME record that points 
documents.example.com to 
docs.example.com. When someone visits 
documents.example.com they will see the exact same content as 
docs.example.com

One of the applications of reverse DNS is as a spam filter. Here's how it works: Typically, a spammer uses an invalid IP address, one that doesn't match the domain name. A reverse DNS lookup program inputs IP addresses of incoming messages to a DNS database. If no valid name is found to match the IP address, the server blocks that message.

Forward DNS lookup is using an Internet domain name to find an IP address. Reverse DNS lookup is using an Internet IP address to find a domain name. When you enter the address for a Web site at your browser (the address is formally called the Uniform Resource Locator, or URL), the address is transmitted to a nearby router which does a forward DNS lookup in a routing table to locate the IP address.

A records are used to point a domain to an IP address. It is the most basic type of DNS record. Basically it is used to find the IP address of a computer connected to the internet from a name.  Allocating a value to an A record is as simple as providing your DNS management panel with an IP address to where the domain or subdomain should point and a TTL.
