Can anyone please help me to understand the meaning/structure of the following TCP/IP network packets?

I need help to figure out what does the sequence of packets tell me about the computer system ( which is 192.168.246.13 ) and the level of security of this computer system?
the last 6 packets are confusing and they don’t make sense to me?!?!?
