Name that plant, part 2

[kake]

Further to my previous post, I have another batch of plants that I hope someone will be able to help me identify.

[IMAGE: A plant (no flowers) in a pot with long green leaves. Some of the leaves towards the top are a pale reddish colour, while others are yellowed and dead at the ends. There is moss growing on the stones that have been used to cover the soil in the pot.]

Bonus questions! Should I worry about the reddish leaves? Should I take the yellowing ones off? Are the reddish ones in fact on their way to becoming yellow ones? Should I get rid of the moss, or will the plant happily coexist with it?

I also have a closeup of the leaves.

Are the dead bits normal for this time of year? Should I take them off or just leave them?

Is this another dianthus?

Does anyone recognise any of these? As previously mentioned, I live in London, UK, if that helps. I would really appreciate any advice!

I have just put an even closer close-up of the leaves on the second one in a comment above.

Thank you for the info on the pieris japonica! What does the moss do to make the plant like it?
