Thank you all!
So here is the result of x-pics identification.
1. Unidentified Alfetta picture taken probably at historic cars event.
D-Type:
"The car in the photo does not have a blanking plate over the top part of the radiator opening. Every picture I have shows such blanking plates. In the 1951 GP as all the cars ran with blanking pltes. Also it is not Farina in the 1951 race as he had a blanking plate then and a coloured nose.
If it is a period shot I speculate that it might have been practice for their first Silverstone appearance (the 1950 GP I think). When they found the cars were running too cool they fitted the blanking plates.
I think it more likely that you are in suggesting its a historic race as the two figures by the car also have a modern look. The photo also looks as though it has been artificially aged."
m.tanney:
"The clothing of the people around and behind the car has a 1970s look to it - check the white bell-bottoms. The driver appears to have a perspex face mask, like the kind Phil Hill used to wear. For one of Road & Track's anniversary issues (25th or 30th), they had him track test of an Alfetta. My guess is that that was when this photo was taken."
WDH74:
"Also, the first pic, of the Alfa Romeo, is definitely not period. The guy leaning over the cockpit on the right, wearing blue jeans, probably confirms it, as does the guy behind him wearing a backwards baseball cap. Where it was shot, who is in the car, year, etc. I've no idea."

2. Fangio and Farina posing during 1951 International Trophy.
Vitesse2:
"Definitely the International Trophy. In "Formula One: unseen archives" there is a picture of Fangio and Farina on page 13, taken within a few minutes of yours Vladimir. Farina's foot is resting on the wheel of a car and he is holding the bag exactly as in the picture above. The location of the picture isn't given, but reference to the one on page 11 shows that Fangio is wearing the same shirt, overall and jacket, while Farina has now discarded his coat: this one is said to be "during a practice at Silverstone in August" 1950."

3. Fagioli, Fangio and Farina before the pits at Monza during 1950 Italian Grand Prix.

Recently I searched through my archives and... Look at what I have found:
The same persons, the same clothing and the Monza pits doubtless, so this puzzle is solved! But I have another one for you: a man in the glasses behind Fagioli's shoulder. His face seems to be known to me so I guess he is one of the Alfa Romeo team mechanics, but I can't remember his name. Any ideas?

4. Wimille on Alfa Romeo 308 in 1946 Coupe de la Resistance at Bois de Boulogne.
Adam F:
"Wimille Alfa 308 photo is May 1946 Bois de Boulogne."

5. Etancelin on Talbo Lago in 1949 British Grand Prix at Silverstone.
GIGLEUX:
"From position of the bazooka on the hood it is first Etancelin's Lago-Talbot #110008, he raced extensively from 1948 to end of 1950.
This car received five times the N.24:
-ACF 1948
-Albi 1948
-British GP 1949
-Pescara 1950
-Italian GP 1950
From the landscape I have a strong presomption for Silverstone and 1949 British GP!"
Adam F:
"I agree that the Etancelin Talbot Lago is Silverstone 1949 British GP - the position of the numbers matches other photos of this car at that event."

6. Alfa Romeo team at pits before 1950 British Grand Prix.
Vitesse2:
"The upper one looks very much like it's the 1950 British GP: AFAIK those driver name boards weren't used in the International Trophy later in the year, but they appear on pits photos I have of the GP."
.ru:
''The Alfa team cars lined up in front of the temporary pits which were located between Abbey and Woodcote. Only Juan Manuel Fangio's car would fail to finish, the other three taking the first three places.'' (Picture and comments reference: The Klemantaski Collection)

7. Gerard during 1950 British Grand Prix.
Vitesse2:
"Motor Sport, June 1950, has a picture of Gerard taken at almost the same spot, but from slightly further along the track, looking back. Points of reference include the oil drum in the background! The car looks identical and lighting conditions look very similar, with sharp shadows, as can also be seen in the MRR picture, even though that is very much darker.
I don't have a picture of Gerard in the International Trophy, but the weather that day went from rainy to overcast, via bright sun on a wet track. The pictures I have show that by the time the track was dry, it was overcast, with virtually no shadows. I'd say it's 99% certain it's taken at the British GP.

8. Farina during 1951 Goodwood Trophy.
Vitesse2:
"Might be at Woodcote at Goodwood I suppose ....
I'd agree it isn't taken at Silverstone in 1950 though - the grille on the car is noticably different."
Roger Clark:
"I am sure that first picture is Goodwood."
***
9. Farina at the finish of 1951 Goodwood Trophy race.
Vitesse2:
"The lower picture is definitely Goodwood."
***
10. Behra on 1952 Grand Prix de Marne at Reims.
Vitesse2:
"The Behra picture is either Pau or Reims - only at those two was there a Gordini numbered 8 as well as Behra in #4. My guess would be Pau."
GIGLEUX:
"No, no, no, sorry Richard but at Pau in 1952 the T16 Gordini was affected to Manzon during practise with N.2. Behra had N.4 but with a T15 (4 cylinders).
It is Reims 1952: note the car has not the grille of the front cowling as that week-end was very hot."

Sorry if I missed someone's suggestions. Thank you once again. I'll be back soon with new X-Pics.
