The delphinium.. cut the flower spike off below the lowest seed pod. It may reflower or build up strength for next year.
The Primula vialii, ( looks like a poker on a stick) will not reflower this year. If you cut off the dead head it will build up strength for next year.
Gazanias,(yellow spike daisy flowers) dead head and they will repeat flower until the frosts.
You have miniature branched sunflowers. As the main ones petals fade, dead head it and side shoots will reflower.
Your indoor plants are Dracaenas, They just look like that.
