Asterisk cards come with different number of ports - and they do for a reason. There are different needs for different applications and manufacturers aim to address them. If you're a beginner, you can order a single port Asterisk card, which is configure with having 1 FXO module. Basically, you would have the functionality of receiving incoming calls, then transfer that call anywhere in your IP network. Of course, while that call is live, your line then would be busy since you only have a single FXO (a single number from your telco as well) handling that call.
A basic setup for you play around with would be a 4 port Asterisk card, with 2 FXO modules and 2 FXS modules. This kind of setup would allow you to receive 2 calls from 2 numbers coming from your telco then transferred to your 2 analog phones connected in your FXS modules, or to an unlimited number of IP or soft phones in your network. Remember that you only need X number of FXS modules for X number of analog devices you have (1:1 ratio). As for IP phones or soft phones, there is virtually no limit. Just make sure they are connected in one network with your Asterisk card.
Now if you're really into, why not order an 8-port card? It basically expands your 4 port supporting much more modules for your applications. If you have 2 lines from telco and have 6 analog phones, simply get an 8 port card, 2 FXO modules, 6 FXS modules, then you're good to go.
The kind of card you need would really depend on how many devices you would connect to your VoIP network. I hope this helps you figure out how many ports do you really need for your Asterisk implementation.
