Answer 1

I propose a powerquery/powerpivot solution like this -

• remove auto filter
• select data
• from table on get&transform group on Data tab

it will look like this

• select name and rollnum both, rightclick group-by. add aggregations like the screenshot

• close and load the data back (it will automatically load to a new sheet in same book)

Note I think you'll these aggregations for each of the day for each of the roll number. It is therefore, advised that create a separate column of date before loading the data into powerquery window and thereafter groupby on name rollnum and date columns.
