While executing the traceroute command, why does the route to same host change at different times of the day?
Why does traceroute not find complete paths to some hosts?
Is it possible to find the route to certain hosts which fail to respond with the ping command?
networking ping traceroute

That's just how the internet works, I am afraid.
Routes can vary in the Internet as the paths are redundant, there are routers/firewalls along the way blocking things for security reasons and even hosts can refuse ICMP packets (pings).
As for the path(s), it is not even guaranteed the packets of a whole TCP transaction with go through the same path.
You can do as pretty much a traceroute based in TCP or UDP packets besides ICMP, if ICMP is being blocked.
For instance:
sudo tcptraceroute www.cnn.com 80

"doubts" is an odd word choice there. quirks, maybe. or possibly "That's just how the internet works".
