Calmly and firmly, the elf walks toward the gangers. He knows he is a stranger to all of them, and that his arrival may seem suspicious. He also knows the kind of people gangers are, and what they truly respect, so his controlled body language make it clear for everyone that he belongs to the streets also.
8 (Charisma) + 4 (Ettiquette) + 3 (Glamour) + 3 (Tailored Pheromone) = 18 dice = 5 hits, no glitch
It's possible that either Glamour or Tailores Pheromones to not come in play; he is walking all the way to where they are, and will be nearby, but he started from quite afar: if one of these are taken out, then the result becomes 4 hits, still no glitch; if both are taken out, then it's 3 hits, no glitch
He also expect that Tony will greet him in a friendly manner when he arrives, which shall improve the elf image with the gang. He knew in the calm pace he is walking he will not arrive there immediately, but showing a confidence look now is more importat than rushing things up.
While strolling among the gangers, he sends a message to Tony: "No need to fear Amy, Tony. You are in your turf, this is your gang; also, we got your back."
Tony seemed reassured, and nodded in greetings toward incoming Fractal. His appearance raised many brows, but other than some hushed 'who's this fragger','idono'. They seemed to accept that people of some importance must somehow appear, and this is just one such case. they wait for for anything to be said or done to build an opinion.
Scanning for com-links on the scary lady (Fronts leader) and her bodyguards:
comp(4)+scan(3)+2tm-2sus=7d6.hits(5)=4
Omar runs scan for radio signals. Not that people in this parts are trying to keep their comunications low and possibly do not use commlink on the daily basics, well still there is lot of entertainment outside and even in Lagos there are some radio receivers in every block. On fact, Omar is surpised a bit by the fact that there is no loud music on gangs home turf, since he always heards a lot about "ghetto" music and its cultural significance.
Using his commlink and signal range of doberman, that walks next to Sam in the hearth of the street, Omar runs scan to find out if there is such a device:
EW(4)+Scan(5)+VR(2) (11d6.hits(5)=4)
Both of the gangers backing up Amy have hidden nodes for their peripherals - AR googles and retractable spurs. Strangely there are no hidden nodes on Amy herself.
Among the crowd around you find five or so passive or hidden commlink nodes, some AR googles or gloves, some music players integrated or no into jewerrly, clothes, a portable trid player unit. In the further circle, there is couple dozens of various state peripherals - from drones, cars, bikes, to fridges, cheap home unit or two,
Even further in range are nodes of local 'businesses' serving virtual sex rooms, hazard nodes serving bordellos, casinos etc.
There is no close music played nearby, must have been turned off, once the fight begun. If you're looking for anything specific, let me know.
The results above is your combined knowledge. As Omar've done signal capture, and Mouse matrix perception.
Then he turns on his radar to check them for weapons and cyberware.
Fairly easy, Sam identifies, that Amy have been quite heavily modifed - sporting wired reflexes, cyber eyes and datajack. She is also having heavy pistol in that holster (but that you could see in plain), they all have pieces of smaller equipment probably 'links. Her gangers, are sporting remingtons 990 and retractable spurs, there also have bunches of metal in the pockets, most probably spare clips.
Among the people around you there is a mixture of knifes, pistols (usually heavy), but also some chains, clubs. There is a lot commlinks and other small pieces of equipments.
