There are a couple of options for getting the information you need. For project info, the easiest way is to use advanced search to get a list of all tasks assigned to specific individuals, which you can then filter by project. You’d have to manually add everyone to the search, but once it’s set up it’ll automatically refresh. Or, you could have separate research reports set up for individuals, depending on the size of your team.
For a full list of all members of a team, you can use the Asana API: https://asana.com/developers/api-reference/teams#users I’m not very confident with the API myself, but I just managed to get a full team list based on the instructions. There’s also a section for projects, if you wanted to use it: https://asana.com/developers/api-reference/projects
It’s probably just a matter of messing around with both options until you find combinations that suit you. If you need further help, just post a reply here and I, or someone else in the community, should be able to point you in the right direction.
