The Chargers agreed to terms with three offensive linemen on one-year deals on Friday.
A former third-round pick, Henderson was out of football last season, but played for the Raiders from 2007-10. He is expected to compete for a backup job.
Dombrowski and Windt were both restricted free agents who signed their tenders to return to the team. Dombrowski, who can play several spots on the line, is expected to be a backup after struggling in the starting lineup a year ago.
