Also, few general strategies to understand for competitive.
Terrorists:
Rush a bombsite together. Yeah, there are other strategies that are valid, but your best bet is to storm one site with all 5 terrorists. There are usually 2 paths for any given site (except for poorly balanced maps like Dust), so you can also consider sending 3 players one way and 2 players another.
Example: on dust2, you can have 3 players rush long A and 2 players rush short A (also known as catwalk).
Counter-Terrorists:
Do not rush all together. Do not rush into the enemy team. Generally, you'll want to have 2 players guarding the paths to either site, and the third player can help guard one of those or watch another chokepoint. As CTs, you basically want to be watching all the chokepoints, and as soon as you know the location of the bomb, call for your team.
Example: on dust2, you can two players guarding B from within B, another player middle guarding both B and short A (also known as catwalk), one player guarding long A, and one player guarding short A.
Besides that, learn the maps, and learn the chokepoints.
