Is this asbestos behind the tile ?

Hello everyone. I was going to start to tackle my 3 season room by rippin down the old walls and putting up greenboard. This room was an add on from the kitchen before I purchased the house. I went to take a peak behind the wall that touches the kitchen and I can see they just covered up the original exterior of the house which is wood shingles with, what I tested is, lead paint. Its a stretch of 18 feet long, 8 feet tall and has a double window into the kitchen and a door. Can I, with all the precautions of lead paint, rip down the old shingles and cover with sheet rock/green board or is there a problem since its an old exterior of the house? My other option is to get rid if all the loose paint and encapsulate and paint it and kinda make it an accent wall to the room. Thanks Picture just shows the room im working with. The left wall has the exterior shingles on it.

I recently purchased my first brick house. I've discovered that it just doesn't work trying to hang items on a nail. As the nail isn't able to go very deep into the wall before it runs into brick. The only other thing I can think of, is using a very small masonry bit with Tapcon's. Assuming that they make Tapcon's small enough. The interior walls are brick in there centers too. Am I correct with this way of thinking ?? Or is there a better way of hanging things on these walls ?? Your advice will be appreciated !!
