Hello,

I think the Bitcoin addresses start with 3,is a multi signature Bitcoin address.
This type of address is used by escrows and business partners.

That is correct, per the wiki article linked by Lutpin:

Addresses can be created that require a combination of multiple private keys. Since these take advantage of newer features, they begin with the newer prefix of 3 instead of the older 1

Address in bitcoin could change anytime. As you saw there it is possible to change standard address with 1 at the beginning and change it to 3.
I think we can see more changes like that in the future when people would use bitcoin even more. There won't be possibility ever for bitcoin to run dry its address pool.

I have been hearing of Xapo, but I am not certain Xapo is as safe as people say.

The problem of xapo is that you can't control your private keys but you can make free transactions which is the opposite of the rest of the other wallets.  Anyway you can use it as a hot wallet that contains few coins/satoshi.
