I want to say for each radius celltracker_group2.time == 10 if radius<=3 and cell_type==4 then GroupCount=GroupCoutn+1

Easily done:

selectedrows = celltracker_group2.time == 10 & celltracker_group2.radius <= 3 & celltracker_group2.celltype == 4;  %logical vector indicating which rows match the condition
celltracker_group2.GroupCount(selectedrows) = celltracker_group2.GroupCount(selectedrows) + 1;  %add 1 to groupcount of the rows that match the condition
