how to read bluetooth UUID?

in the manufacturer the number shown is in Decimal ,right ?
so 76 - Creative Technology Ltd.
6 - Microsoft?

I read the link - jsut want to be sure
there is no way to know what is the service been send right ?
If I look at the first device
and take look at the second group of 4 digits :"e0e1"
this is the sevice name ? and this is not a standart one ?
it could mean 'sensor value' (for example ....)?
if this I understadn it correct - where is the value of it?

also if the 4 digits were "0x2A80" that mean that the service was Age? (according to GATT) , and where was the value of this ?

Thanks ,
