Answer 1

You can store the values as a list or tuple.

info = {'John': [111111], 'Mike': ['222222']}
info_b = {'John':'21/may/1998','Mike':'14/feb/1996'}
for k, v in info.items():
    v.append(info_b.get(k, ''))

info
# returns:
{'John': [111111, '21/may/1998'], 'Mike': ['222222', '14/feb/1996']}

Answer 2

Well, you should point 'John' to a dictionary (Or create class to represent people(?)) for every person of yours since you try to hold for them multiple features that represent them, and in order to make your data understandable you gotta reconstruct the json to be like that:

info = {'John': {'id': 111111, 'birthday':'21/may/1998'},'Mike':{'id':222222,'birthday':'14/feb/1996'}}

Answer 3

Try making the value of each person a list

info = {"John": [111111], "Mike": [222222]}

count = 0
for item in info.values():
    birthday = input(f"{[*info.keys()][count]}'s birthday:\n")
    item.append(birthday)
    count += 1

print(info)

Answer 4

Dict it's all about key and value.

The best way to perform without using Class is to set the pair key/value for each Person.

Example:

#First you create two different Person
info = [{'name': "John", 'id': 111111}, {'name': "Mike", 'id': 222222}]

#If you want update the birthday of the first Person (John) you can do it like that.
info[0]["birthday"] = "21/may/1998"

#And for Mike you modify the second item in the list 
info[1]["birthday"] = "13/june/1996"
