You only need one sip.conf file and one extensions.conf, you just may 
find it simpler to have 2.

Yeah, if the handsets are sip handsets, then you just need a 
context=line in each to segregate them in the dialplan.

You may be able to have the sip clients with the same name and have 
asterisk match by host, but I don't know if this still works. (Haven't 
tried it for a very long time).

They can all be in the same file, as I said before, using multiple 
though may make administration a bit simpler.

In your example you'd need an extensions.conf with containing nothing 
more than.

#include /etc/asterisk/extensions_customerA.conf
#include /etc/asterisk/extensions_customerB.conf
#include /etc/asterisk/extensions_customerC.conf

Set the context in sip.conf for the handset in company A to point to a 
context that can dial the phones in company A.

Eg:

sip.conf:

[general]
bindport = 5060
bindaddr = 0.0.0.0

[CustomerA-100]
type=friend
secret=password
context=outgoingcompanya
accountcode=companya		;useful for billing using cdr
.. (then codec stuff and voicemail settings)

[CustomerA-101]
type=friend
secret=password
context=outgoingcompanya
accountcode=companya		;useful for billing using cdr
.. (then codec stuff and voicemail settings)

[CustomerB-100]
type=friend
secret=password
context=outgoingcompanyb
accountcode=companya		;useful for billing using cdr
.. (then codec stuff and voicemail settings)

[CustomerB-101]
type=friend
secret=password
context=outgoingcompanyb
accountcode=companya		;useful for billing using cdr
.. (then codec stuff and voicemail settings)

etc ...

extensions.conf:

[outgoingcompanya]
exten => _10.,1,Dial(SIP/CustomerA-${EXTEN})

[outgoingcompanyb]
exten => _10.,1,Dial(SIP/CustomerB-${EXTEN})

Obviously this is all oversimplified, but you get the gist.

Try reading about sip.conf and extensions.conf won www.voip-info.org and 
reading the sample configuration files that come with asterisk.
