Answer 1

oak??

Answer 2

It's an arborvitae.  They're very common trees for close to houses, so I doubt that it'll crack your foundation or break pipes.  

Answer 3

It looks like the junipers I have and the root systems are not invasive .they can get very tall.

Answer 4

Looks like an abrorvitae, sometimes called Cedar.  Thuja occidentalis would be the botanical name.

The root system on those is relatively small compared to the tree.  Not a lot of horizontal spread.  Your foundation should be fine.  And as long as the gas line doesn't go right under it, that should be fine too.
