Can anyone help to identify these following components on the board.

You encircle a lot of components.
In the right 2 circles are probably 2 buck or boost regulators, given the capacitors and inductors there too.
However, the photo does not show the marking on the components so we cannot state anything more.

Ok Thankyou so much

I agree, the components on right look like regulators. On the left - interesting, especially so many vias around them ... I would think they could be also some kind of regulator (but only a few small capacitors is around ... so I am not sure) or a high current switch maybe (but too many legs for this ... so again I am not sure). What is MA MB marking on the header pins?

Even, I am also trying to explore about the devices may be some buck converters.may be some connections from motor or so coming to the terminal blocks.
I only have thi PC with someone and no design files where in we can locate these.

Thankyou so much Robert.

Are there markings on the components or did the manufacturer remove them?

Yes the manufacturer have removed them

Layout wise it look a bit like this https://www.infineon.com/assets/row/public/documents/10/49/infineon-bts621l1-e3128a-ds-en.pdf?fileId=5546d4625a888733015aa3c7be2b1010
