All that can be done with current WP/BP versions. If you’re new to WP/BP, you’d have to:
– do some reading https://codex.buddypress.org/home/ and
– testing on an installation already set up at http://testbp.org/ or set up your own installation and
– diving into code yourself or hiring someone to do it.

As for plugins, it is good practice to install plugins which are compatible with your WP/BP version – you’d see it noted in plugin information https://buddypress.org/extend/plugins/.
