Private limited company with less than 5 employees. Are minimum wages applicable? Also what about ESI and PF?
Please let me know what are the things I should take care of in terms of HR.

Dear Friend,
It seems you have taken a charge of HR in Private Limited company having less than 5 employees and you want to know what the labour laws are applicable to you. You are a beginner.
Labour Laws applicable to you are:
1. Shops & Estb Act,
2. Payment of Wages Act,
3. Minimum Wage Act,
4. Labour Welfare Act (See your State Law),
5. Professional Tax
You need to maintain following registers and notices:
1. Muster roll,
2. Wage register,
3. Salary slips,
4. Leave Book / Card,
5. Notice of working hours, weekly offs, rates of min.wages, date of payment, person responsible for payment of wages etc.,
6. I.Card to all employees
You need to maintain personal files of the employees with their basic details such as employment blank with proof, photo, appointment letter etc.
Read and understand the above applicable laws with rules applicable to your State. Apart from this, you need to have glance on Industrial Dispute Act.
PF and ESI Act is not applicable to you right now. But you still need to read and understand all the labour laws. Understand the features of all the labour enactment. Acquire basic knowledge of HR functioning.
You have not mentioned your qualification. Add professional qualification in your profile.

Dear Friend,
I read your title now. You are asking for salary slip structure.
I divide the salary slip in 6 parts. They are
1. Employee master information including rates of salary components
2. days payable i.e. work days, offs / holidays, leaves
3. Earning components with total of it
4. Deduction components with total of it
5. Net payment &
6. Proof of payment with revenue stamp.
This you will not find in any of the books or in links.
Doing this pandemic I am at home idle and therefore I afford to spend this much time on this forum since last 3 months. But from tomorrow onwards I have decided to start my office. Once I start my office, I won't be in position to spend any time on this forum.

Yes
You need to maintain personal files of the employees with their basic details such as medical record, attendance record, pay roll (of,esi etc.) employment blank with proof, photo, appointment letter etc.
