Yes, you can. Previously Adsense did not allow you to use other contextual advertising networks on the same pages as Adsense. They have since changed that and allow other contextual networks provided that the ads do not look similar to Adsense ads.
If you read the TOS you will know this is allowed. In general you can run AdSense with every other ad network as far as the ads are not contextual and don't look & feel like AdSense. Good luck!
