are we sure sockets have fuse? we are talking about wall socket. not those square plug into wall socket (extension socket).
as far as i know plug & extension socket have fuse but not wall sockets.
i don't know how thick the connectors inside are, but surely thicker than 2.5mm2? just wire uses copper not sure connector uses what.
according to BS the total consumption should be no more than 20A combined. the test is runned based on 1 socket on 14A and 1 on 6A for 4 hours.
but Schneider says 13A rated so i'm not sure what they mean.
If you're running heating appliance then this is a major concern. If just electronics house hold appliance rarely hit the limit of the fuse. They are efficient nowadays.

If cannot over 13amp, then i combine few more extension then safe or not? example combine 3 or 4 extension together is that ok and safe?
Depends on cumulative load. Modern circuit breaker is sensitive.
