OK, about the hand signs, original and second photo.
My son said he never saw the sign done by the big guy ( I'll call him Buddha ) but it might be a gang sign used in Tijuana. He gave me some suggestions on what to look for on Google. I used these for the original photo and the last photo you posted Comm I/C.
Keep in mind that these people were probably not American gang members. Most signs found on internet are american based gangs. One can see photos of many hand signs here, but they are gangs from across the US who created variations on other gang signs, depending upon history.

I could find nothing on the first guy's hand sign... nada. That doesn't mean it's not, just that it's not shown on the internet or connected to the known gangs we hear about. I saw the same hand sign but pointed down multiple times... but to raise the hand up, none.
In looking all over and using a bunch of time today because I am too curious sometime, I think our Buddha there is saying, in 1st photo, the reverse of a gang sign because I could not find one sign with the crossed fingers and crossed thumbs together in an upward position. It might be his FU to the old days of when he was in some obscure mexican gang that has no signs posted anywhere on the internet... like "I am out and clean."
In the second photo, I could find nothing on the girl's middle finger going down like that.
Mr Buddha is probably just giving the photographer the finger for bothering them again with photo shoots, lol.
As far as the other the second photo hand signs of the guys in the back, the V with thumbs crossed, that is a common sign, even in some gangs, for victory. Some people do it sideways, or fingers u with back or palm side showing. I also saw one place sight that identified the same sign as meaning "deuces". Only the urban dictionary mentions a meaning for it

In searching for deuce sign I got a bunch of 'peace' type photos, or maybe hello? I don't know but many people are doing the chunking up the deuce, so I looked that up. Same thing... like "hey" " peace" " hello" seam to be what deuce means and when one does it, it's called chunking up the deuce.
Chunk up the Deuce!
Chuckin up the deuces means to throw up the peace sign.

This two finger hand sign thing
What does the two fingers pointed horizontally hand sign mean?
Comment:
That would be refered to as "chunking up the duece". You would usually do it when leaving a spot...I guess. If you're white you take pictures of yourself doing it with that stupid look on your face on myspace. When something like that or certain terms crossover to popular culture that usually means it's played out and only said by lames...that reminds me please...enough with the no homo cam'ron did it to death already. I've been hearing people say "peace out" which I thought died back in 91 or something.

Some people apparently use it as a FU with a smile, lol
I tried. Here is a link for all the images on the deuce + sign keywords
