1- the family has a name and reputation and he was expected to live up to it
2- what photos there are = the few that exist
3- a social lion is, I think, someone who is very popular
4- it sounds as if it means 'gained'- can you supply a bit more context
4- she explained her case well

Thans for your reply. However, still I have questions about the second one--what photos... You explained what photos as few exist. Could you be more specific( I mean gramatically)?
Thanks in advance!

It's just an expression similar to 'such photos as there are'.
