Can I safely allow these Chatroulette connections or should I block them?

Please see attached log. I keep getting alerts from your firewall when I use Chatroulette. Are these connections safe to allow and make a rule allowing them? What are these connections? Thank you

The question about ingoing traffic isnt, if its safe. (Who should know who will knock on your door tomorrow?)
The question is: Is it necessary to allow that?
If everything runs fine, answer is: No.

Try to use the stealth port wizard setting 3. You dont have to ask yourself again about unrequested ingoing traffic.
Only servers and peer to peer could need specific rules to allow ingoing anyway.

thank you. I did not know about the stealth port option 3. ;D
