Romcenter

Using Romcenter, is any scan of my MAME 0.273 non-merged roms folder able to show if any rom needs BIOS, Samples and CHD?

I haven't tried it myself with the latest versions of MAME, but you can try it out, it should work.

print my test, romcenter capable detect issues files chd, samples and bios in my roms folder mame 0.273 non merged?

I'm not sure i understand the question. Romcenter (RC) is capable of detecting all of the file types you mention, as long as they have been properly defined in the datafile. A datafile generated by MAME itself should have proper definitions, so RC should detect all these types. If it has been generated manually, there is no guarantee what will RC detect.

I have a folder of roms mame 0.273 non merged downloaded from a website and the same website where I downloaded the roms I downloaded the dat file mame 0.273 non merged, I inserted the dat and the roms folder for the scan in the romcenter in this scan the romcenter is able to show if any bios, chd and sample files are missing in any of my games?

Normally, it should. You could also generate the 0.273 database from mame itself to be more sure.

the official dat of mame 273 is not the same as the one created by the non merged fulset downloaded in pleasuredome

I don't know if mame has non merged dat

IIRC, it does. Check this post. I'd suggest you set both options to "Ignore" and then recheck your roms (DON'T FIX, just check). If they still appear yellow in a game, then try to play it in the emulator, it will probably not work.

As a general rule, the only datafile you should trust is the one generated from MAME. If with that datafile you roms appear as yellow, they should be fixed. Also to be "proper", you should leave the Case Options in Settings as they appear in the image, "Datafile".
