My questions is just about possibility that any owner of Electrum server can see our IP address and our coins address/es.

To answer this question: yes, owners can log ip's and addresses on several levels... It's so easy anybody could do this.
Either by running a reverse proxy (like nginx) in front of the electrum server and logging everything, or by modifying the electrum server's sourcecode to add extra logging (most, if not all, implementations are open source), or just from the OS level by capturing the packages over electrum's port (wireshark can capture the packages and automatically decrypt them using the keyfile used to setup ssl).

If you're really paranoid, i'd suggest using electrs (https://github.com/romanz/electrs/), that way you don't have to add txindex=1 to your node's config and use an alias or shortcut to start electrum using only your own node.

Using tor is a good alternative to, but you have to make sure you always start the tor proxy, and never open electrum without using said proxy...
