Looks like nginx is listening to port 80,you should stop nginx with this command sudo service nginx stopand start apache after.

Edit: after short discussion we figured out the problem was in: wrong config in /etc/hosts and running nginx server. everything fixed after moving apache to another port and adding correct hostname in hosts file.

we didt installed nginx, we used only apache..... – spylh9999ggr Nov 29 '17 at 07:35
From last picture you gave it clearly shows that port 80 is taken by nginx – AsenM Nov 29 '17 at 07:36
oh, sorry, i dont have much idea about server as i am developer, i will check the link you gave.... – spylh9999ggr Nov 29 '17 at 07:36
If this won't be a production server and will be used only for development you can easy change the port of apache to 8888 and use it that way – AsenM Nov 29 '17 at 07:41

Into the report of sudo service apache2 restart I can see two problems. The first one is the message sudo: unable to resolve host <host-name>. Probably the solution of that is here: When I run a sudo command it says unable to resolve host.

The second one as @AsenM noticed is that some other service (nginx) is listen to the port 80: make_sock: could not bind to address: ...:80. Usually you can use the command sudo lsof -i -n -P to investigate which service on which port listen.
