Answer 1

You can create a template field and bind two fields like this.
<asp:TemplateField HeaderText="Airlinepenality" SortExpression="ddlAirlinePenality">
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%#Eval("AirlinePenality")+ " " + Eval("ddlAirlinePenality")%>' ></asp:Label>
</ItemTemplate>

Answer 2

you are using Bound field, we can merge two columns by TemplateField only, So better you can merge that two columns in your query,
try like below...
Query:
SELECT UnusedTicketAmount, ddlUnusedAmount,
cast(1.25 as varchar) + ' ' + cast(172813.99 as varchar) as AirlinePenality,
NetRefundProcess,ddlNetRefundProcess,RefundableCommission
ddlRefundableCommission,CouponRefunded,RefundType
Gridview
<asp:BoundField DataField="UnusedTicketAmount" HeaderText="UnusedTicketAmount" />
<asp:BoundField DataField="ddlUnusedAmount" HeaderText="ddlUnusedAmount" />
<asp:BoundField DataField="AirlinePenality" HeaderText="AirlinePenality" />
<asp:BoundField DataField="NetRefundProcess" HeaderText="NetRefundProcess" />
<asp:BoundField DataField="ddlNetRefundProcess" HeaderText="ddlNetRefundProcess" />
<asp:BoundField DataField="RefundableCommission" HeaderText="RefundableCommission" />
<asp:BoundField DataField="ddlRefundableCommission" HeaderText="ddlRefundableCommission" />
<asp:BoundField DataField="CouponRefunded" HeaderText="CouponRefunded" />
<asp:BoundField DataField="RefundType" HeaderText="RefundType" />

Answer 3

Suppose you want to merge last three columns of your grid then you can also use the below code:
protected void grdAirTicketList_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Header)
{
e.Row.Cells[8].Visible = false;
e.Row.Cells[7].Visible = false;
e.Row.Cells[6].Attributes.Add("colspan", "3");
}
}
This means your column named 'CouponRefunded' and 'RefundType' will not be visible and 'ddlRefundableCommission' will be visible with colspan 3.
