name = input ("Enter name :")
gender = input("are you a m/M or a f/F:")
while gender != 'M' or gender != 'm' or gender != 'f' or gender != 'F':

if gender in ['F', 'f']:
    print("Hello Miss",name,",")

If the gender is m for example, then the condition while gender != 'M' or gender != 'm' or gender != 'f' or gender != 'F': is always True so it'll execute the code below the while block infinite times. In fact you don't even need the while statement for this program.

gender = input("are you a m/M or a f/F:")
if gender in ['M', 'm']:
    print("Hello Mr",name,",")
if gender in ['F', 'f']:
    print("Hello Miss",name,",")

I could have used if-elif-else construct as well.

name = input ("Enter name :")
gender = input("are you a m/M or a f/F:")
if gender in ['M', 'm']:
    print("Hello Mr",name,",")
elif gender in ['F', 'f']:
    print("Hello Miss",name,",")
else:
    print("Invalid Input")

You're looking for something like this?
It allows you to give inputs two times and print the output. You can change the condition to give more inputs than 2.

i = 0
while i <2:
    name = input ("Enter name :")
    gender = input("are you a m/M or a f/F:")
    if gender in ['M', 'm']:
        print("Hello Mr",name,",")
    elif gender in ['F', 'f']:
        print("Hello Miss",name,",")
    i  = 1
