Sorry, I realize my mistake. I need the entire characters on column 1 to categorize the data in the output file;

Code:
aa123 344-456, 34-67
bb34 34-90,23-100,1-89
d3 0-12
e55 45-678,78-90,56-90

It was the half-baked specification that made people resort to assumptions based on your sample output. On top, RavinderSingh13's proposals in post#2 DO provide for the entire first field. Adapt Don Cragun's proposal to allow for the entire field1:
Code:
awk '
last != $1      {if (NR > 1) print ""
                 last = $1
                 printf("%s\t%s-%s", last, $2, $3)
                 next
                }
                {printf(",%s-%s", $2, $3)
                }
END             {if (NR > 0) printf RS
                }
' file
