You could either say "on his bicycle" "on a bicycle" or "on their bicycle" You could say "I saw terrible things in my sleep last night" or "I saw terrible things while I was sleeping last night"

You can start a conversation in several ways in English. "Hello. How are you?" "Hi. What's up?" "What's up?" "Hey, how have you been?"

I'll give some examples. "We are in Oklahoma." "The dog is on the porch." "They are at the store." All can be used to describe location or position.

They all generally mean the same thing, all of them are past tense. Had been is usually used to describe something that was occurring, but isn't anymore. It is only used with the he/she form. Ex: "She had been working the night shift at her job." Has been is also past tense, but it could imply that it is still occurring. Also only used for the he/she form. "She has been really sad lately." Have been is also past tense, but is only used for the I/they form. "I have been really tired." "They have been busy lately." Hope this helps! That's a hard question LOL!

You could say, "Hi everyone! Just wanting to wish you guys a Happy New Year filled with good health, happiness and many blessings!"

No. Turning is not appropriate for what you are trying to say. "Turn right" "Take the next right turn" "Take the next turn on the right"

"What does Lily look like?" Is asking someone to describe her appearance. "How does Lily look?" Is asking for an opinion of her appearance. "Have you seen my daughter Lily?" "I don't know, what does Lily look like?" (Followed by a description) "Lily got a new dress today. How does she look?" (Followed by an opinion)

People say it jokingly like "I accidentally knocked over my neighbors trash can with my car today!" "You are the worst!" It means like, "you are bad" or "you are a trouble maker" but not in a rude way.
