2: Customer will use web browser (websocket compatible of course) and enter address of the KAMAILIO Box or we shall need another KAMAILIO to statelessly forward the call to next available operator using Hunt Group or similar scheme?
kamailio could route the call to a call center application, which can easily be written in sems, for example.
4: Last, but not the least, how will the users send request for login from browser? (assuming they have accounts created in the DB on Kamailio Box running WEBSOCKET supported KAMAILIO)
if the user needs to login to your web page, then the websocket sip application can use the same credentials for making the call via kamailio.
