Is there anyone else? would you like to have something else? would you like to have anything else? which one is correct? please tell me , thank you very much!Thanks for all of your answers, but I still confused, what kind of sentence you will use "someone and something"？ what kind of sentence you will use "anyone and anything"? Is there a rule?

when I arrived home I was surprised to see that the front door to my house was already open...... when I arrived home I was surprised to see that the front door to my house was already open.But the door wasn't damaged, It's nine oclock,who is in my house? I rang the doorbell, but noone answered.I pushed the door lightly, it was dark in the hall, I went though the living room, there was nothing changed.that's really weird. then I went upstairs to looked at the bedroom.there was nothing wrong either.I have no idea what was going on here in my house. I thought maybe I didn't lock my door when I was leaving this morning.Yeah, maybe I didn't do it, I've felt upset for a couple of days, because I've fallen in love with a young beautiful girl since 3 month ago. but she's disappeared. I didn't know why she went and didn't tell me why. I thought maybe she's the reason why I didn't lock my door.I'm thinking about if I'm going to call the police .But suddenly I saw a little light in my back yard, I open the window and look at the garden, there are plenty of candles, they were arranged into a big heart, and my girl is standing inside and smiling to me.I've just remembered today is my birthday.
