Only software project owners or facilitators have access to this page. If you're a software project owner or facilitator, click on the "Manage members" link in the software view.
On the "Manage members" page, a list of all project members can be found. Change the boxes next to the members you want to edit. Then click on "apply these changes." The users will receive a mail to let them know of the changes.

Sometimes, you won't be able to check / uncheck boxes. This is because these members haven't been approved yet. You'll see "approve" and "deny" links under their name then.
In another case, it's because the member you want to alter, is the software project owner. As he's the owner, you can't demote them from facilitator, and can't remove them from the project. A moderator's intervention is required if these changes are necessary.
A release manager can manage (create and edit) project releases. He can also upload artifacts within the maven repository (nexus).
