How can I retrieve the list of delta users using Microsoft Graph API for which his/her group or event data is changed? Users delta api gives the list of users for which their contact related information is changed but not when his/her skills/events/groups data is changed e.g. if few users add a new skill then in incremental mode which api I can use to get these delta users details?

You cannot get notifications about skills. If you try to call Graph API delta endpoint for users
GET https://graph.microsoft.com/v1.0/users/delta?$select=skills
It will return the error message
Invalid request for delta query: for this entity set, $expand/$select is not supported for the following properties: skills
For events, Graph API supports only notifications for specific user, not for all users.
GET /me/calendarView/delta?startDateTime={start_datetime}&endDateTime={end_datetime}
GET /users/{id}/calendarView/delta?startDateTime={start_datetime}&endDateTime={end_datetime}
For groups, you can call the following endpoint
GET https://graph.microsoft.com/v1.0/groups/delta
The response contains the members@delta property which includes the ids of member objects in the group. If the @odata.type is #microsoft.graph.user then id is the identifier of the user.
"members@delta": [
{
"@odata.type": "#microsoft.graph.user",
"id": "693acd06-2877-4339-8ade-b704261fe7a0"
},
{
"@odata.type": "#microsoft.graph.user",
"id": "49320844-be99-4164-8167-87ff5d047ace"
}
