When Cerberus got loose and was wreaking havoc in the Underworld, Hades made a deal with Hercules that he could take his wife, Deianeira, back to the land of the living if he caught Cerberus. Hercules did so in (Hercules in the Underworld).
Hades was in love with Persephone, the daughter of Demeter. However, Demeter did not approve of Hades. When Hades became frustrated with Demeter's interference, he "kidnapped" Persephone and brought her to the Underworld. Demeter was furious. She caused a winter storm which killed many crops and people in the land of the living. She asked for Hercules' help to go to the Underworld and retrieve Persephone. Hercules discovered that Persephone had not been taken against her will. She was in love with Hades. Hercules negotiated a deal wherein Persephone would spend half the year with Hades and the other half with Demeter (HTLJ "The Other Side").
Feeling that Hercules owed him because he missed Persephone during her time away from the Underworld, Hades asked the hero to assist when Sisyphus tricked Timuron into taking his place in Tartarus. Hades gave Hercules three days to bring the real Sisyphus to the Underworld. He told the hero he couldn't do it himself because he was too busy as Zeus had cut his staff to two and Ares was sending numerous dead from the Thracian Wars. Once Hercules managed to get Sisyphus to the Underworld Hades agreed to let Timuron have 24 hours of life so he could say goodbye to his wife, Daphne (HTLJ "Highway to Hades").
When Iolaus was killed by the Enforcer II, Hades agreed to let Hercules take Iolaus back to the land of the living if he could defeat the Enforcer II by sunset. The other condition of the bargain was that Hercules had to take the original Enforcer with him so that she could prove herself worthy of either the Elysian Fields or Tartarus (HTLJ "Not Fade Away").
Hades seems be to one of the only respectable gods of the Olympian Pantheon.

It appears that Hades and Mephistopheles knows one another Because when Mortals commit unspeakable & Deadly crimes Hades find Tarturas itself too good for them so he sends them to Mephistopheles directly to be punished in Hell itself.
