So, you don't know the difference between acceleration and velocity, thats cool. To let you know what they are, velocity is speed/time thus things like miles/hour are velocity, where as acceleration isn't the same thing. In the scenario that you gave, they acceleration of them are the same, whereas the velocity is different. Thus with the acceleration being what it is (gravity, i.e. -9.81m/s) they do both have the same initial acceleration. They DON'T have the same initial velocity.

Yes, if you account for friction in the air, they will reach the same terminal velocity, eventually. However the rock will accelerate to its terminal velocity at 9.8 m/s^2. The bullet would accelerate at somewhere around 10^5 m/s^2 out of a gun (rough estimate), and then slow down to terminal velocity. With that in mind the bullet would cover a huge distance before slowing down to the same speed as the rock, and considering that at terminal velocity they have to move at the same speed (once again, assuming equal surface area and other factors) the extra distance initially covered by the bullet slowing down to that velocity will be the difference between when the bullet and the rock hit the ground.
Sorry about a wall of text, but that's the best short way that I can explain it.

If you do not take account the different friction in the air between the bullet and the rock then you also can't involve terminal velocity. Terminal velocity is reached when the friction between the object and the air put an equal amount of force on the object as the gravity does pulling the object down.

Generally in such an example the objects aren't dropped from a height where they would reach terminal velocity anyway. Also every time I've seen such an example it is used in a different, and more clear way. Allow me to break it down.
If you take a bullet and a rock, as anon did in his post, then he should've just said that he dropped both of them. That way people may think that the heavier, bigger rock would hit the ground first, but based on physics both the objects would accelerate at the same rate (once again, assuming that we're in a vacuum with no friction) and as such they would hit the ground at the same time.
If you want to use an example where one object is thrown (or fired) horizontally OP should've kept the thrown (or fired) object the same as the one dropped. So he should've said that he fired a bullet horizontally, and dropped another one, and both of them hit the ground at the same time. Or he could've said that he threw a rock horizontally and dropped another rock. That way he would cover the confusing factors.

Wait, you seriously couldn't bring any metal device inside your school ? That's pretty fucked up in my opinion.
So I guess you learned to create programs ? I got a friend in my current class who's a huge TI geek and create mini-games and programs to help in physics and maths. He just needs to enter the prompted variables and the calculator does all the shit for him in a matter of milliseconds ! He even sold some of his programs 5 euros per person last year in his class
