Questions about prepositions-when,while and as
I am expecting somebody can reply my questions,thanks a lot.
When,while and as
a) What are the differences between them,they all mean that during a period and something is happening.
1) We were attacked with rotten eggs by a group of gangsters while/when/as passing by the street.
2) I used to visit my grandfather twice a month while/when/as I was young.
3) He has been there while/when/as we just arrived the airport.
Which preposition are correct for these sentences?
b) Like and as
1)All of us are dressed as/like ghosts and witches to celebrate Halloween in a crazy midnight party.
2)He makes an announcement to employees like/as he is the management director of the company.
Like and as are the same ? However,I consider that as is more formal than like in English.
Thank you in advance.
