Please find my answers below:

1) Ok, fine.

2) NCAP_AFC has the indexes NCAP_AFC(r,y,p,cg,tsl).  Here r=region, y=year, p=process, cg=commgrp and tsl=timeslice level.  The shorthand notation NCAP_AFC(NRG,DAYNITE) just tells that cg='NRG' and tsl='DAYNITE'.  NCAP_AFC(NRG,DAYNITE) tells that cg='ACT' and tsl='DAYNITE'. You can specify cg in the CommGrp column, and tsl in the Timeslice column. You could also use the header NCAP_AFC~DAYNITE.  So, in one row you could write 'NRG' in the CommGrp column and put the value 1 under the column NCAP_AFC~DAYNITE.  And then in a second row you could write 'ACT' in the CommGrp column and put the value 0.625 under the column NCAP_AFC~DAYNITE. It is easy, but as always, check the parameters in Browse.

3) NCAP_AFC(NRG,DAYNITE)=1 defines a DAYNITE level availability factor for the NRG flows (NRG means energy). An availability factor of 1 (=100%) means that the full capacity can be used. The full capacity is 60 MW.  So, with an availability factor of 1 (=100%) you can discharge max. 60 MW of energy output in any timeslice, and charge energy into the storage with max. 60 MW power in any timeslice.
NCAP_AFC(ACT,DAYNITE)= 0.625 defines a DAYNITE level availability factor for the activity (ACT refers to the activity).  The activity represents the storage level.  By convention, in a DAYNITE level storage an availability factor of 1 (100%) would correspond to a maximum storage level of CAP × 24 h = 60 MW × 24 h = 1440 MWh. Therefore (for a storage with maximum storage level of 900 MWh), an availability factor of 0.625 would correspond to a maximum storage level of 60 MW × 24 h × 0.625 = 900 MWh. See the documentation, section 4.3.7 Availability factors for storage processes.

NCAP_AFC can only be used for UP/FX availability factors.  Therefore, for defining the minimum storage level of 200 MWh, NCAP_AF(ANNUAL, LO)=0.138889 is needed, because an availability factor of 0.138889 for the storage level would correspond to a storage level of 60 MW × 24 h × 0.1388889 = 200 MWh.  NCAP_AF is always levelized, and this can therefore be defined for the ANNUAL timeslice only.
