You are using the Debian/Ubuntu packaging and the above is part of that.
Also they are very helpful so you don't want to get rid of them.

From your previous post:

root(at)elfero:~# pg_lsclusters
Ver Cluster Port Status Owner Data directory
Log file
9.5 main 5432 online postgres
/mnt/HC_Volume_8755337/postgresql/9.5/main
/var/log/postgresql/postgresql-9.5-main.log
10 main 5433 down postgres /var/lib/postgresql/10/main
/var/log/postgresql/postgresql-10-main.log

So, the 10 instance is not running and the 9.5 instance is listening on
the default port. At this point I would leave things as they are.
