Sure,  see the following sample code:

this is from a pagetableblock which has this button on every row of the table

<apex:commandButton value="Accept"  action="{!CreateAcceptDealAction}" >
<apex:param name="ADealID" assignto="{!AdealID}" value="{!DealMapWrapper[d].deal.id}"></apex:param> </apex:commandButton>

When we click on the commandbutton"Accept" - the record ID of the record on this particular row is assigned to the property "ADealID" of the controller

in the controller: public String Adeal {get;set;}

You can use the apex:param tag with commandbutton such that you can assign any value to a property in the controller using the attributes of this tag:
