2. hood dented and unable to open

Bonnet straight buy used one. See if Mudah has it

3. front bumper slight dent

If you ask shop, they will push out sand and repaint. If it costs RM200, you might wanna try luck at mudah for second hand bumper.

4. car plate full replacement

Any car plate shop can do. Last time i changed for my Corolla is RM17 for standard number & design. Special design one i dunno.

Ketuk? Can but too expensive because time consuming. Some shop probably won't do also or charge higher. By the time you reach paint job and if it cost more than RM500, you really will be better off economically looking for used one that is same year and model as yours. You haven't factored in the bumper yet. Very likely you can spend less than RM500 for bumper and bonnet if you look for used. And also save a lot of time not having the car in paint booth.

If the shop is not busy, just 1 day. Some shops take up to a week.

Speaking from my experience crash with bike last year. Right fender gone, door crumpled, right side mirror broken& front bumper scratched.

I also did not go the insurance route.

So i bought

Original used fender (not same color) - RM50

Side mirror bracket -RM 60

Knock door, repaint bumper, fender & door - RM500

Total : RM 610.00

But if my fender was same color i could get the knocking & paint job at RM400.

Your case if you can secure a used bonet in same original color (RM150-450 based on mudah price), you save a lot of money on knocking and only need to paint bumper.

I went to a workshop near my place in PJ. But some say can get cheaper than what i got. Do remember that i bought the fender myself at Mudah.
