I have a 5 months old baby and milk supply is low. Do I introduce formula milk? If yes please guide me.

He also has diaper rash that is not clearing and the neck region is somehow cracked.

I am confused.

Please help.

You can introduce formula milk until baby reaches 6 months. Then you start with porridge like maize or rice porridge and proceed to other solids later.
A rash that is not clearing could indicate an infection so please see your doctor for treatment.
