Jaydeep, the Newsfeed plugin works in such a way that it shows only the profile owner actions. But the other users can comment on the profile and comment the Newsfeed content of the View Profile page.
So, if I understand you correctly, you want for example, when the User A open its own View Profile page he can see all posts and comments in the Newsfeed. But when the User B opens the View Profile page of the User A he can only see the actions of the User A (but he can't see any comments)
Or may be you want to restrict the comments and not to show all comments in the Newsfeed except actions of the profile owner.
In both ways it requires the custom code modification. But as an easy way we can suggest you to hide the comment input text area and the item's comment area using CSS styles.
You may try the CSS style code below to see the effect I'm talking about. Go to the Admin Area>Appearance>Edit Theme>CSS tab and paste this code:
.profile-NEWSFEED_CMP_UserFeedWidget textarea.ow_newsfeed_status_input { display: none !important; }
.profile-NEWSFEED_CMP_UserFeedWidget .newsfeed-comments-cont.ow_newsfeed_features { display: none; }
.profile-NEWSFEED_CMP_UserFeedWidget .ow_newsfeed_control { display: none; }
