Yes you can. Log into the web admin UI the access point and navigate to either "Single Point Setup / Sessions" (if you have multiple access points in a cluster) or "Status and Statistics / Associated Clients". The "Sessions" view will should you the MAC addresses of all clients associated with any access point in your cluster. The "Associated Clients" view will show you the MAC addresses of clients associated with the particular access point into which you logged in. Given the MAC addresses you may want to then connect to your DHCP server (likely your router in a small setup) and determine the IP address and perhaps name information for the clients of interest.
