Cisco wireless products have the option to offer to the wireless clients both encryption methods, TKIP and AES and even WEP on the same SSID. This can be configured on the GUI and CLI but what you have to be aware and be careful is that this is not the standard. Even though Cisco can offer this, some clients won't understand that, they will get confused and disconnect or just not be able ro connect at all.
We are talking about encryption here not authentication so to answer your question: yes, you can configure several encryption methods on the same vlan but it is not a best practice and regarding authentication, it is not possible to configure different authentication methods on the same SSID.
You have to understand the standards... WPAv1 uses TKIP and WPAv2 uses AES. So clients configured for WPA/TKIP will not connect to an ssid with WPA2/TKIP. Apple devices are notorious for not working with both enabled and it would be something you would need to test.
