No it is only their are needs to be multiple summon signs in the area

yeah i was able to summon two phantoms (players) and sola ire for ornstein and slough on NG with a level 75 character

Yes you can summon multiple people without any items npc and or players. Just have to be able to fine a summon sign.

You can summon multiple phantoms using the dried finger

Your most likely offline, check your settings and if it's DS1 you'll get a message asking at the start whether or not if you want to play onjline

The game asks you if you want to play online at the start. You must be in human form in dark souls one to be invaded, and in dark souls 2 it is more likely when you are human, To confirm you are both online and in human form, try finding white signs from coop players in the ground. If it works, you are online.
Note you can only be invaded when your world boss is alive

Yo if you need co-op on dark souls say where

Pretty sure yes. I've been trying to stick around the Undead Parish to help people out with the gargoyles, even though I'm a bit over leveled and I've been summoned a couple times. I've already killed the Capra demon.

how do you set a password? there shouldn't be any password in dark souls 1

You can not set a password in DS!

There's gonna be a password though.. I hope it's not like ds3, because the fact that they had less health didn't make up for the fact y hat they would be able to use weapons and spells wich should be impossible at the host's level. And it's sooooooooooo pleasant to invade 3 guys and two of them being level 500 or something while you're level 30.

It's not a spell always, and the other person can always just leave the match

the host can't leave :p

and yes, buffing is an attack. im not gonna let a falchion buffer buff without consequence. buffing is for noobs and for people with noob builds.

Buffing is not for noobs or for noob builds, then by your logic Anon backstabing, power withing, wrath of gods, dark beads, twop, persuers, the hornet ring, poise, anything with bleed, so on and so on are all for noobs and everyone in dsr is a noob. Sounds more like you're just salty from dying so much. This game is about advantage so why would you limit yourself and the host decided to be invaded by going online and being human, you can always play offline or be hollowed. Just like how an invader takes a risk of being ganked when invading. Also PvP Etiquette should not be listen to, anything goes in a fight.

your opinion is false.
