puncture in the skin that you are putting salt water into it.
Saline is often used for some injections anyway, and it is a perfect practise fluid.
Hypothetically, yes it can. HOWEVER, using sterile water for practicing IM injections will HURT. The sterile water is not isotonic with the cells in your body and will result in both pain and small uncontrolled muscle spasms that will subside in a few minutes. Please if possible use an isotonic sterile saline solution as this should not produce any pain or side effects.
Antibiotics, is a generalized answer, however there are different types of antibiotics. There are Bacteriostatic Agents which answer your question in that they inhibit the growth of bacteria which is a microorganism Then there are bactericidal agents (bacteriocide) and they kill bacteria which is a microorganism Agents having the suffix -cidal kill organisms, agents having the suffix -static merely inhibit their growth and reproduction.

For example, many nursing schools will kick you out of the program if they find that you have been practicing on people who are not in the program or covered patients. Many schools won't even allow students to practice on each other in a school setting or anywhere else. it is a HUGE liability and infection issue!! If you injected someone and they got infected, they could sue you. In addition, you could be fined for practicing medicine without a license because you don't have a prescription for whatever you are injecting. Saline is now considered a drug under federal law.

The general consensus is that these injections don't really work, and instead are marketed inaccurately as a cheap and easy solution. You're better off maintaining a healthy lifestyle and diet.
The gauge of the needle, what the needle is being used for (IV, tattoo, blood draw, injection, etc.) all have an impact on the sensation experienced when a needle penetrates the skin. With injections in particular, the solution's thickness will definitely contribute to it. The thicker the solution, the more painful.
The role of a General Practice is that of initial presentation of a health, be it medical or other to a Medical Doctor. From an initial assessment of the problem a direction as to how to find a solution will be made.
