The Bible forbids people that they cannot talk to the relatives that have died, meaning we cannot communicate with the dead people, but does the Bible forbid to communicate with angels?
The Bible says nothing for or against trying to communicate with angels. Since all such communications recorded in the Bible were with angels sent by God to a person, I am not sure it is possible to communicate with angels without them making the first contact.
I am also wondering what sort of communication a person would desire with an angel. Since an angel is a messenger from God, and since we have direct access to God through prayer, I see no value in initiating communication with angels. If you had a direct phone line to the President of the United States why would you want to try to get a message to him by contacting a clerk in the White House mailroom?
