Do any of these Steam software titles run without internet connection?
On the Steam website (through the links you listed) the only one listing "broadband internet connection" as a requirement is TR 2013. The other two have no requirements for internet connection indicated.

That said, I have not played any of those games so I cannot certify that the specifications are correct. But I would think they are pretty careful with those, given all the debate going on regarding internet connection requirements for gaming.

On the other hand, I am quite sure that if you want to host multiplayer games with your friends you DO need some kind of LAN connection (wi-fi or wired).
