Upgrade from 5 sp to 7 sp
I plan to upgrade multiple freehub 5 sp (14-18-21-24-28) to shimano 7 speed (11-13-15-18-21-24-28).
What modification I need to do:
1. Change right shifter to 7 sp,
2. Replace freehub from 5 sp to 7 sp,
3. I have 8 sp chain,
...
Best Regards,
PD.

#1. Yes
#2. Are you sure you have a 5s freehub and not a freewheel? Sounds like you need a new rear wheel.
#3. Will work fine
Your frame's rear triangle may need to be spread, also, and if you use the same rear wheel it will need to be redished.

Additionally, if your rear shifter is not indexed - i.e. friction based - then you can still use that. If it is a friction shifter, you can basically run any number of gears you want if you fulfill the other criteria.

1. It is MTB frame with 135 spacing (but I will check). Spreading frame is not neccessary.
2. "Rear wheel it will need to be redished" but in my LBS think it is not necessary ?!?
It is neccessary or not ?
3. Does my old RD (old SIS) will work with 11 tooth top gear?

135 OLD = no frame spreading and most likely no redishing as well
Can you find a 7 speed freewheel with an 11t cog? 12's are out there, 13's are common
Your RD should work, but there's really no way to tell for sure until you try it. (edited out)

i jam my thumbs up and back into the tubes. this way i can point my fingers straight out in front to split the wind and attain an even more aero profile, and the usual fixed gear - zen - connectedness feeling through the drivetrain is multiplied ten fold because my thumbs become one with the tubing.

The 7-speed freewheel is wider than the 5-speed you currently have. You will need to change the location of the spacers on the axle to install the new freewheel. This means that the wheel will have to be redished to get the axle centered again. I did this last year with an '84 Miyata.
