import re
text = '{"mob":"1154098431","type":"user","allowOrder":false,"prev":1}'

newstring = '"allowOrder":true,"'
#newstring = '"mob":"nonblocked",'

reg = '"allowOrder":(.*?),"|"mob":"(.*?)",'
r = re.compile(reg,re.DOTALL)
result = r.sub(newstring, text)

print (result)

im trying to matching and replacing multiple regex patterns with exact values can someone help me to achieve this

You should parse the JSON rather than trying to use regex for this. Luckily that's real straightforward.

import json

text = '{"mob":"1154098431","type":"user","allowOrder":false,"prev":1}'
obj = json.loads(text)  # "loads" means "load string"

if 'allowOrder' in obj:
    obj['allowOrder'] = True
if 'mob' in obj:
    obj['mob'] = 'nonblocked'

result = json.dumps(obj)  # "dumps" means "dump to string"

assert '{"mob": "nonblocked", "type": "user", "allowOrder": true, "prev": 1}' == result
