There are 4 directors.

PF has no shares and is therefore unable to participate in the rights issue.
CC took up all his entitlement.
AG took up part of his entitlement.
AJ did not take up any of his entitlement.

You will not see any directors taking up any shares greater than their entitlement as that requires shareholder approval. The most a director can take up in a rights issue without shareholder approval is their entitlement.

GH is not a director so we will only get to know his shareholding when the Annual Report is published by 31 March 2016.

Please DYOR.
