or:

select b.FName + ' ' + b.Lname as FullName, count(*) as Count_of
from table_b as b
inner join table_a as a on b.id = a.id
group by b.FName + ' ' + b.Lname

by the way, if you want all names, then the count of the orders placed
then use either of the above

however, if you are only interested in those names that have ordered, then reverse the table sequence e.g.

select b.FName + ' ' + b.Lname as FullName, count(*) as Count_of
from table_a as a
inner join table_b as b on a.id = b.id
group by b.FName + ' ' + b.Lname
