Unfortunately, not. Skype allows more than 2 users if you pay.
Can you make 3 way call on skype free w/o Video?
Yes, you can.
Audio only conference calls with up to 25 users are free. However, group video calls require that at least one of the participants has Premium account.
The link to the instruction on how to set up a group audio call, in Ruwim's post, above, is still valid and includes step-by-step screen shots for you to refer to.
yes you could make a call with upto 10 people without video .
