As long as the Half-Life games makes Valve some money, they won't change a winning recipe. So, there will almost for sure be another Half-Life game. yes the first half life was a great success and so where the expansion packs for the PC. The sequel game Half life 2 has also been a huge success and so have ep 1 and ep 2, and soon there will be a ep 3 Half Life 2 episode 3 will be the last in the series, Half Life 2 Ep 1, 2 and 3 are actually Half Life 3, Valve split the game into three so that it wouldn't take them 6 to 10 years to make life Half Life 2 did

you start with half life 2, then you play half life 2 episode 1, then you play half life 2 episode 2, so you are basically playing them in the order they are in at the game select screen (where you choose any of the half life games, portal or tf2)
No, only Half-Life and Half-Life: Decay.
