Recommended minimum connection times

Delta: 30-minute minimum connection time. Southwest: At least 30 minutes if you have checked bags.

Will Delta wait for connecting passengers?

It varies. They will often wait a little while, especially if it's the last flight of the day and even moreso if there are multiple passengers making the same connection. I've had Delta wait for me after inbound connection delays on several occasions.
