After applying GC for my brother, Can he work in US ? on which status?

On H1B status. Your I-130 alone gives him no immigration benefits.

Can I apply green card for my brothers wife too?

When a visa # is available, she will be able to get one as a derivative beneficiary, as can his minor children.

3) how long GC process will take?

8-12 years, generally.
