Answer:
Alone I am 24th with a friend I am 20. Another friend and I am unclean.
I am a mountain at night, meadow at day. What am I?
I cannot be felt, seen or touched. Yet I can be found in everybody. My existence is always in debate, yet I have my own style of music. What am I?
I make a living following the wealthy and beautiful.
Although a human shape I wear Mother I never had; And though no sense nor life I share in finest silks I'm clad. By every miss I'm valued much beloved and highly prized; still my cruel fate is such by boys I am often despised.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
