The tree in your first two photos looks like a loblolly pine, which is a native tree. https://www.marylandbiodiversity.com/viewSpecies.php?species=331
A key to identifying pines is to look at the bundles of needles (called fascicles). Loblolly pines have three or sometimes two needles per fascicle. http://www.sfrc.ufl.edu/extension/4h/trees/Loblolly_pine/index.html
The second plant looks like a Chamaecyparis. There is one type that is native to this area (Atlantic white cedar) -- but now rare.
Many of the species used in landscapes and gardens are non-native Asian varieties -- but they are not known to be invasive.
