How do I fix these electrical problems? on 1995 Oldsmobile Cutlass Ciera

I've got a 1995 Olds Cutlass Ciera SL 3.1 V6 with just over 70K miles. The only problems I'm having are with the exterior lights. The right brake light stays on constantly, the front and rear right turn signals turn on but don't blink, the front marker lights aren't working, and the third brake light (the one above the trunk)doesn't work. Help, please?
