@Meenakshi Vattanavar Thank you for posting your query on Microsoft Q&A. PFB answer for your queries:

2. What is the maximum requests per Azure AD B2C tenant per minute by default? 1200/min
3. What is the maximum requests per Azure AD B2C tenant per sec by default? 200/sec
4. Is there any request limit per client id in azure ? The cost of POST, PATCH, and DELETE operations on the applications request path depends on the signInAudience type. For apps where the signInAudience is AzureADMyOrg or AzureADMultipleOrgs, the cost is 70,000 requests per 5 minutes; while for apps where the signInAudience is AzureADandPersonalMicrosoftAccount or PersonalMicrosoftAccount, the cost is 60 requests per minute.
5. What are any other criteria's for calculating rate limit ? For B2C: Tokens/sec = 200/requests-consumed
6. What kind of requests are included while counting the rate limit ? These could be found Azure Active Directory B2C service limits and restrictions
7. What if we want to change the rate limit then how can it be done ? No these cannot be changed as these are calculated as per license https://azure.microsoft.com/en-us/pricing/details/active-directory/external-identities/
