Sand it smooth and paint the handrail "safety yellow"?
Get a copy of the galvanizing spec and see if it says anything about the topic?
Ask the galvanizers about it?

implementing coating seems good idea,can any one help and give me the material name please

You are right, the problem that Client is not accepting the current status and he is considering this shape is not meeting the HSE requirements, we have huge quantity which is already erected, we need to find a solution away from cutting and welding

SYSTEM 10: EPOXY COATING OVER HDG
BASE METAL -HDG STEEL
CLEANING -TO SSPC-SP 1
WASH -POLYCLUTCH 97-687 BY PPG
PRIMER -AMERLOCK 400 TWO COMPONENT EPOXY BY PPG
TOPCOAT -AMERCOAT 450H TWO COMPONENT ALIPHATIC POLYURETHANE TOPCOAT BY PPG
SYSTEM 11: EPOXY COATING OVER HDG (ALTERNATIVE)
BASE METAL -HDG STEEL
CLEANING -TO SSPC-SP 1
PRIMER -DEVOE DEVRAN 201 EPOXY
TOPCOAT -DEVOE DEVTHANE 379 URETHANE
The topcoat can be safety yellow... What HSE requirements and why is it not conforming?

You’re not doing a very good job of explaining to us or showing in your photos, exactly what the various problems are. You should get with your customer and actually list the various types of roughness and sharp spots, and approx. quantities, etc., so you have an idea of what tools will be used most and are most important. The customer has every right to be concerned about these problems on handrails and the like, when his workers are going to cut their hands when using the handrails.
It looks like you have one size of pipe handrail, and then maybe several different roughness problems on them. I would be looking for some tools and light machines which semi-skilled workers could use on every handrail assembly on the project to clean these rough and sharp spots up. The single size pipe should simplify you tooling needs. Auto body shops have some shaping and finishing tools for non-flat surfaces which might work for some of the problems. Maybe some woodworking or light machine shop tools like belt sanders, flap sanding wheels, angle grinders, various other grinders, routers, etc. might work. The trick is to mount these to shaped bases, matching the pipe dia. so the workers can’t do more damage than they do good. Maybe a special shaped cutter/grinder and tool base will slide along, right on the pipe shape, and just clean up the high spots. This all takes some imagination and engineering judgement on your end. Certainly, I would involve your other subs who played a part in this mess.

did the client accept the drawings before assembly ? (I'm guessing not)
I'm guessing that maybe the hand rail should have been welded to the offending flange ?
another day in paradise, or is paradise one day closer ?
RE: Sharp edge of handrail
We always use pipes the same size as the rail to avoid this issue. Just want to be clear; is this a handrail or a guardrail (fall protection). There's a big difference.

The handrail in the second photo appears smooth; I'm not sure what the problem is with it.

If someone were to fall of the stairs and bashed their heads on that edge, it could possibly cost them their life.
Reweld the angle so that the parallel edge is underneath the hand rail, and the perpendicular (to the handrail) side points outwards. Better still, choose pipe for the posts.

RE: Sharp edge of handrail
The conclusion you should draw from all the posts is - no one is at all sure what the "problem" is.
