Is it possible or ok to use only one integration user to connect multiple external applications to salesforce? What would happen if i am using only one salesforce integration user for multiple external applications and all external application request some data/query from salesforce at same time?

Using a single integration user is certainly possible however you need to keep a couple of things in mind
- Data visibility
- Permissions
- tracking
Data visibility: every application can also see the data of the other applications as it all comes from the same user.
Permissions: Applications will most likely have broader permissions than they need as the permissions will be based on the need of all applications and not just 1 application.
Tracking: It will be harder, maybe even impossible to see the origin of a change if multiple applications can create and update accounts for example.
For these reasons it is best practice to use multiple users for external applications. On your other question: You can multiple API requests at the same time with a single user. just be aware that you are still bound to the concurrent API request limit on requests over 20 seconds just like when you work with multiple users.
