I've never heard of SIP and QLLC  . PLP, afaik, is a network layer protocol, do it doesn't fit. HDLC and 802.2 (LLC) are definitely related to SDLC. (OK, I searched on the web, and QLLC seems to be related to SDLC too.)

2)To list the network protocols and the number of users and hosts,you can use the followingjob aid.To which category would "frame Relay" belong?
This question doesn't make too much sense; however, the only choice that fits with "Frame Relay" is "name of protocol".
