How to support "like friends photos" for Facebook user using Facebook APIs or FQLs?
The REST API is deprecated, and the Graph API should be used whenever it´s possible. FQL only if there is no other/good way with the Graph API.
About liking Photos, see here: https://developers.facebook.com/docs/reference/api/photo/
You can like a photo by issuing a HTTP POST request to PHOTO_ID/likes
connection with the publish_stream permission. No parameters
necessary.

I want to get who commented or liked to my post on Facebook through facebook api.
I used Facebook Graph API and could get post_id.
And used this endpoint: {POST_ID}/comments, but it returned only my comments.
Is there any way to get other's comments with user id?
One of our feature is to display the posts of our facebook friend. And that is made possible by Facebook Query Langauge FQL. Unfortunately FQL has been deprecated by FB in favor of Graph API which has stricter permissions. A possible replacement is the Graphs API user_posts permission where we can query user posts via user feed.
However the docs says:
"Your app needs user_posts permission from the person who created the post or the person tagged in the post."
Are there still alternative to get get user posts even without users permissions?
You only should be able to access friend's posts if your friends gave at least user_friends and user_posts permission to the same app.
If so, you'll only have access to those friend's posts, not to all your friends. An no, there's no workyround. Facebook did this on purpose with the introduction of the Graph API v2.0.

A Facebook user's screennames are not available through the Graph API or FQL. See this thread from Facebook's forum, where a Facebook employee confirms this fact.
