Can more than 2 be connected to the Trio and are they wireless?

Not more than 2 (unless you daisy-chain Trios); no they are not wireless

Can i use these mics with my 8800 when connected via usb to a pc? im mostly using it this way, and not like a regular phone.

no, they have a specific Polycom plug

Need longer cables for these. What connnector/cable do they use?

Polycom cables. they sell longer cables for that microphone

Can the polycom realpresence trio 8800 ip conference phone work with 4 of the expansion mic's?

Pretty sure it cannot, by itself. It can only take up to two expansion microphones directly attached. However - Polycom recently released firmware that will reportedly let you daisy chain an add'l Trio 8800 - which would allow you to add another phone, and possibly another pair of expansion microphones to the secondary Trio. https://community.polycom.com/t5/VoIP-SIP-Phones/FAQ-Daisy-chaining-a-Polycom-Trio/td-p/102702 https://support.polycom.com/content/dam/polycom-support/products/voice/realpresence-trio/release-notes/en/polycom-trio-rn-ucs-5-8-0-aa.pdf
