Please tell me whether right or wrong

Whether this is correct depends on what kind of hall this is.

If it's a lecture hall, with a specified number of chairs for people to sit in, then place is fine (although room works, too). If it's a hall in somebody's house, where there aren't predefined spots for things (i.e. places) then room is the correct word.

I'm an American English speaker, but I suspect this answer is the same in British English.

Number 2 is not wrong. 'Place' can mean 'a particular portion of space normally occupied by a person or thing' (cf Collins dictionary). We can also think of a place in a hall (any hall, not just a lecture hall or the like, contra Peter Shor) as an available or unoccupied spot to put an object or person.

Also, numbers 1, 5, and 7 are not so much as wrong ('entirely ungrammatical' as some of the others) as outdated or rare these days. A certain portion of the native speaking population still talks about 'a Xerox' as 'a copy made on a xerographic copying machine' (cf Random House dictionary et al).

Number 10 is not entirely ungrammatical.
