Can someone tell me what each of the symbols mean in the multiplayer screen?

1. ?
2. Looks like a yellow tent. ?
3. Says 64 so I assume it is saying this server hosts 64 player maps, but under players it lists 64. Seems redundant.
4. I assume it means you can use vox communications, but I would have thought that was a given.
5. Under players I see it lists the number of players, how many players it can hold, but what is the number in the parentheses for?
6. Lastly why would I mark the box BattleCommo for under Internet filters.
I have seen some other symbols that I did not know, but when I logged on this morning there was not too many others.
Thanks in advance.
