Application Presentation Session
Rip and BGP is in Application layer Ospf is in Transport Layer
Application layer protocols: DNS and HTTP Transport layer protocols: UDP for DNS and TCP for HTTP
application
The Application layer uses protocols that are implemented within applications and services. While applications provide people with a way to create messages and Application layer services establish an interface to the network, protocols provide the rules and formats that govern how data is treated.
There are more than 3 protocols at the application layer. Three well-known protocols are: HTTP - web page traffic FTP - file transfer traffic SMTP - email transfer
Presentation
Some end user applications are "Network Aware" , meaning they implement the application layer protocols and are able to communicate directly with the lower layers of the protocol stack. Email clients and web browsers are examples of these applications.

HTTP Belongs to the Application layer. Other transfer protocols like POP,FTP,SMTP etc also belongs to this layer
There are many more than three protocols which can operate at the application layer. Some of these are; Telnet FTP TFTP SMTP IMAP POP DNS RARP BOOTP SNMP CMOT
No, At each layer, protocols perform servers unique to that layer. While performing those services, the protocols also interact with protocols in the layers directly above and below. In addition, at the top of the OSI model, Application layer protocols interact with the software you use. At the bottom, Phsyical layer services act on the networking cables and connectors to issue and receive signals.
