|I can't tell if you are trying to get all three number strings, separated by a comma, into one cell or get each string into it's own cell.|
In either case, start with this:
1 - Select the column
2 - Use Data...Text-To-Columns...Delimited...Next
3 - Check Space, Comma, and enter a ( in the Other box
This should give you this:
A B C D E F G H
1 Tel: +81) -- 0321-4229815 Hassan) 0309-4123454 0342-4356789 Amjad)
If all you want is the values in D, F and G, just delete the other columns.
If you really need 0321-4229815, 0309-4123454, 0342-4356789 in a single cell, use this formula after following the Text-To-Columns steps
=D1 & ", " & F1 & ", " & G1
