Is it possible to take a 72dpi RGB photo and transform it in a very good resolution photo for printing? I have to use one photo in my company and no one seems to find the original. I tried to change the mode and resolution to 300dpi and CMYK but looks really bad.

WORKING WITH RESOLUTION

Yep, that's life!
You cannot improve a resolution easily on an images. The only reliably way is to take the photo again at a higher resolution.
Take this to the extreme mentally and you'll see how that works. Imagine you took a photo at 1px by 1px. You'd have only 1 pixel. That could be any particular colour.
Now try to improve that resolution to create a photo of an orchestra. No chance. You cannot create information that is not in the original photo (short of importing it from another photo but then you'd have to have the other photo already).

There is one chance - dependent on the physical size of the pic. If it's big - inches high by wide - try boosting to 300 dpi and then reducing the size accordingly. Sometimes pics from megapixel cameras are VERY large at print size.

I think jmgalvin meant to increase resolution without resampling. If the image is large enough at 72 ppi, this can work with no change in image resolution and no increase in pixelation. Also, remember that most printers produce a very nice image with as little as 150ppi. 300ppi is really not necessary. 72 to 150 is a lot more doable than 72 to 300.
... what you are asking doesn't really mean anything. it is like saying "i have some peas and want to fill up a glass with them - will they fill the glass up?"
how big is the glass?
72 d.p.i. really doesn't mean much. it is only a product of pixels / output size. the '72 dpi image' could be 1 metre square - and would happily print out a 1/4 that size (and larger - as kiddpete states)
basically the answer is this:- have a look at the current output size of the image - in its unaltered state of 72 dpi - and you can be confident that it will be fine to use at up to 1/4 of that size

OK. Sorry not answering. Now I am here in the office and my images are exactly:
a) 2.222W x 1.667H (in) 160X120 pixels
b) 3W x 2.25H (in) 180X135 pixels
c) 5.403W x 3.611H (in) 389X260 pixels
and they have to be 2.95x2.95 in
Seems that difference between the original and the one I want for the final is not too big what leaves me without options, right? I tried to get best results with Auto option and the results are also bad.

There is no way you are going to get those images to print with any quality at that size.
The third-party Photoshop filters that can 'up-res' a photo could not help even these small images.

That's funny, I can't see any stars anywhere.
Does that mean that no-one gave any information? ;-)
