Yes! There is!

If you're looking to teleport somebody, you can determine the direction that they're looking at with this syntax of the /tp command.

/tp @p [x] [y] [z] [x-look] [y-look]

If you're looking to select somebody looking in a certain direction, you can use the rx, rxm, ry and rym selector arguments.
For each selector, a float is required as the value to look for. The ry and rx arguments look for a player with a rotation lower than the given value, while the rxm and rym arguments look for a player with a rotation greater than the given value.

• The rx and rxm arguments test for the player's horizontal rotation.
  -90.0 being that he/she is looking straight down and 90.0 for straight up.
• The ry amd rym arguments test for the player's vertical rotation; whether they are looking North, South, East or West.
  This system branches from the South direction (0d) and moves into negative/positive; East (-90d)/West (90d) and North (180d/-180d).
  It also allows for in-betweens of multiples of 90 degrees, allowing freedom in testing for certain rotations, for example: 45d is South West.

For example, if I would like to test for a player that is looking North West, and straight ahead (at ground level), I would test for a rx and rxm of 0 (directly ahead) and a ry and rym of somewhere between North (180d) and West (90d); 135 degrees.

 /testfor @a[rx=0,rxm=0,ry=135,rym=135] ...

Just note, that this command tests for exact rotation, which can be really hard to reach. It'd be better to give leeway either side, for example: 5 degrees.

 /testfor @a[rx=5,rxm=-5,ry=140,rym=130] ...

If not, are you able to count how many players that are on a specific team in a set radius and then say that number through /tellraw?

This is also achievable. This time, add the team selector to your command, and to count, get each player to /execute @a[...] ~ ~ ~ scoreboard players add dummy count 1, assuming that you have a dummy player to take the count, have the score set to 0 and your counting scoreboard is count.
