Custom Tweaks needed

1) Trying to change the “Like” button in the following page, before the “Comment”, and “Delete” buttons:

websiturl.com/g/founder

2) The Bio under the profile photo in the above mentioned page is added using the following solution:

https://premium.wpmudev.org/forums/topic/add-buddypress-profile-field-to-front-end

Would like to know whether there is any way to limit the number of words displayed under Bio to 5.
