What should I do if I'm looking to generate a new multi-signature address ?

[SLRman]

I have an electrum wallet installed on my computer and I wish to use a random address from it to use for the escrow. Is it a bad idea ?
In the electrum wallet I can see the private and public keys of the address so it should be all good ? t


though I don't understand why I can see 3 different public keys to be related to one address?  why is there 3 ?  
.. upon generating a new multi-sig address, I'm asked for a public key but I'm not sure which to choose of that 3 for that, please help ? or just choose random?

Thanks!

No (at least not the address part, I cant judge whether you are suitable to do escrow or not).

2-3 multi sig addresses have 3 public keys and 3 private keys. Any 2 private keys can spend the coins.

You need to get the public keys from the other 2. You also need make sure you all use the same order, e.g.

pubkey#1
pubkey#2
pubkey#3

and

pubkey#2
pubkey#3
pubkey#1

result in different addresses.

Yes ,https://xapo.com/ IE Xapo .They do have multi sig wallets usually the addresses starting with digit 3xxx. Other such service is https://copay.io/ ,haven't really used any of them ,you can do your researches.Not really recommended to use an online wallet for multi-sig purposes.Try electrum ,a better alternative,here is a small tutorial on how you can create a multi-sig wallet using it  http://docs.electrum.org/en/latest/multisig.html

Bitgo and Coinkite also provide multisig wallet creation I believe but its not safe, its better if you create a multisig wallet safely on your desktop or an offline machine because the whole point of having a multisig is to make sure your coins are more secure, isn't it?
