Something similar to counter exists in the game: If you maximize coffee, you become immune to damage for 3 seconds. Having the strong maxed up to also gives you immunity.
Tea is already a thing. If you have coffee (maximized or not) it heals you 1 - 3 health.
Pocket attack is similar to throwing cups
Restoring ammo is already a feature, you have a chance of getting an ammo drop.
Criticize is bragging maxed out. The enemies shoot themselves if you use the brag.
Not to be rude or anything, but your ideas are revamped versions of already existing ones.
