does it have selectable channel

No it comes with a default channel already and you can't change the channel.

What the frequency that the microfone Works at. i Will use in Brazil

The mic frequency will automatically adjust itself. No need to look for the right frequency.

I need to buy 5. Can they all be different frequencies?

I believe so. I have 2 operating without problem at the same location. I do not recall a frequency adjustment so it must be automatic. There may be an upper count limit. Ask the manufacturer.

Can three single wms40 mini vocal set be operate at the same time without conflicts frequency or channel?

As long as they are all different ABCD bands of this model. I have three for my wedding DJ setup and I run ABC bands with absolutely no interference. Have been doing this for about 3 years now. No dropouts up to about 100 feet line of sight and no failures yet. I even have to AKG's from 20 years ago I use as well if needed for lavalier applications that still work perfectly. Big AKG fan here.
