Unit, Stop loss, Trailing stop, Upper bound, Lower bound, margin

I am reading several books including Candlesticks by Mr.Corbitt and two by Steve Nison.

When I access my broker or possible NDD and I want to enter a bid, I see the above amounts needing to be entered. In fact, it allows me to set defaults as well.

1.00 is 100,000 and .001 is 1,000 or a micro.Correct?

I would like to know how to set these. No calculator on mobile ( which is where I will likely be trading, has these.)

I am also reading Babypips and if this is in after middle school. I will eventually read about it.

Some guidance is requested.
